    Abstract:
    Polarization-sensitive photodetectors, based on anisotropic semiconductors, have exhibited wide advantages in specialized applications, such as astronomy, remote sensing, and polarization-division multiplexing. For the active layer of polarization-sensitive photodetectors, recent researches focus on two-dimensional (2D) organic-inorganic hybrid perovskites, where inorganic slabs and organic spacers are alternatively arranged in parallel layered structures. Compared with inorganic 2D materials, importantly, the solution accessibility of hybrid perovskites makes it possible to obtain their large crystals at low cost, offering exciting opportunities to incorporate crystal out-of-plane anisotropy for polarization-sensitive photodetection. However, limited by the absorption anisotropy of the material structure, polarization sensitivity of such a device remains low. Thus, a new strategy to design 2D hybrid perovskites with large anisotropy for polarization-sensitive photodetection is urgently needed.

    Polarization-sensitive photodetection using 2D/3D perovskite heterostructure crystal


    Beijing, China | Posted on May 4th, 2021

    Heterostructures provide a clue to address this challenge. On the one hand, construction of heterostructures can improve the optical absorption and free-carrier densities of the composite. On the other hand, the built-in electric field at the heterojunction can spatially separate the photogenerated electron-hole pairs, significantly reducing the recombination rate and further enhancing the sensitivity for polarization-sensitive photodetectors. Therefore, constructing single-crystalline heterostructures of anisotropic 2D hybrid perovskites would realize devices with high polarization sensitivity.

    In a new research article published in the Beijing-based National Science Review, scientists at the Fujian Institute of Research on the Structure of Matter, Chinese Academy of Sciences create a 2D/3D heterostructure crystal, combining the 2D hybrid perovskite with its 3D counterpart; and achieve polarization-sensitive photodetection with record-high performance. Different from the previous work, devices based on the heterostructure crystal deliberately leverage the anisotropy of 2D perovskite and the built-in electric field of heterostructure, permitting the first demonstration of a perovskite heterostructure-based polarization-sensitive photodetector that operates without the need for external energy supply. Notably, the polarization sensitivity of the device surpasses all of the reported perovskite-based devices; and can be competitive with conventional inorganic heterostructure-based photodetectors. Further studies disclose that the built-in electric field formed at the heterojunction can efficiently separate those photogenerated excitons, reducing their recombination rate and therefore enhancing the performance of the resulting polarization-sensitive photodetector.

    “High polarization sensitivity is successfully achieved in self-driven polarization-sensitive photodetector based on a single-crystalline 2D/3D hybrid perovskite heterostructure which is grown via a delicate solution method,” the author claims, “This innovative study broadens the choice of materials that can be used for high-performance polarization-sensitive photodetectors, and correspondingly, the design strategies.”

    Abstract:
    As more private data is stored and shared digitally, researchers are exploring new ways to protect data against attacks from bad actors. Current silicon technology exploits microscopic differences between computing components to create secure keys, but artificial intelligence (AI) techniques can be used to predict these keys and gain access to data. Now, Penn State researchers have designed a way to make the encrypted keys harder to crack.

    Graphene key for novel hardware security


    University Park, PA | Posted on May 10th, 2021

    Led by Saptarshi Das, assistant professor of engineering science and mechanics, the researchers used graphene — a layer of carbon one atom thick — to develop a novel low-power, scalable, reconfigurable hardware security device with significant resilience to AI attacks. They published their findings in Nature Electronics today (May 10).

    “There has been more and more breaching of private data recently,” Das said. “We developed a new hardware security device that could eventually be implemented to protect these data across industries and sectors.”

    The device, called a physically unclonable function (PUF), is the first demonstration of a graphene-based PUF, according to the researchers. The physical and electrical properties of graphene, as well as the fabrication process, make the novel PUF more energy-efficient, scalable, and secure against AI attacks that pose a threat to silicon PUFs.

    The team first fabricated nearly 2,000 identical graphene transistors, which switch current on and off in a circuit. Despite their structural similarity, the transistors’ electrical conductivity varied due to the inherent randomness arising from the production process. While such variation is typically a drawback for electronic devices, it’s a desirable quality for a PUF not shared by silicon-based devices.

    After the graphene transistors were implemented into PUFs, the researchers modeled their characteristics to create a simulation of 64 million graphene-based PUFs. To test the PUFs’ security, Das and his team used machine learning, a method that allows AI to study a system and find new patterns. The researchers trained the AI with the graphene PUF simulation data, testing to see if the AI could use this training to make predictions about the encrypted data and reveal system insecurities.

    “Neural networks are very good at developing a model from a huge amount of data, even if humans are unable to,” Das said. “We found that AI could not develop a model, and it was not possible for the encryption process to be learned.”

    This resistance to machine learning attacks makes the PUF more secure because potential hackers could not use breached data to reverse engineer a device for future exploitation, Das said. Even if the key could be predicted, the graphene PUF could generate a new key through a reconfiguration process requiring no additional hardware or replacement of components.

    “Normally, once a system’s security has been compromised, it is permanently compromised,” said Akhil Dodda, an engineering science and mechanics graduate student conducting research under Das’s mentorship. “We developed a scheme where such a compromised system could be reconfigured and used again, adding tamper resistance as another security feature.”

    With these features, as well as the capacity to operate across a wide range of temperatures, the graphene-based PUF could be used in a variety of applications. Further research can open pathways for its use in flexible and printable electronics, household devices and more.

    Paper co-authors include Dodda, Shiva Subbulakshmi Radhakrishnan, Thomas Schranghamer and Drew Buzzell from Penn State; and Parijat Sengupta from Purdue University. Das is also affiliated with the Penn State Department of Materials Science and Engineering and the Materials Research Institute.

    “I am pleased to report continued growth in our net asset value per share (NAV) as of March 31, 2021, to $10.60, the highest level in over six years,” said Kevin M. Rendino, Chief Executive Officer of 180. “This growth was powered by our continued strong performance in our public market investment strategy that generated a gross total return of +28.3% in the first quarter of 2021.1 Our separately managed account (SMA) had strong performance as well, generating a gross total return of +20.7%. If this were the end of 2021, we would generate approximately $2 million in carried interest from the SMA, and net performance for the SMA would be 14.5%.2 I remind investors that this potential carried interest is not included in our reported NAV as of the end of the first quarter of 2021. We ended the quarter with approximately $114 million in assets under management in aggregate in 180 and our SMA, available to be deployed in our public market investment strategy. I am proud of this 5.5x increase in scale we have built at 180 since starting in 2017. We continue to believe our Graham and Dodd investment philosophy, coupled with our activist approach, will lead to enhanced shareholder value creation for all of our TURN shareholders.”

    “Q2 2021 has started off positive for 180 and our SMA,” added Daniel B. Wolfe, President of 180. As of May 10, 2021, 180’s cash3 and securities of publicly traded companies increased to approximately $77.0 million, or $7.42 per share, and our SMA increased to approximately $41.5 million in asset value. These increases bring our current assets to be deployed in our public market investment strategy to approximately $118.5 million. We remind investors that it remains too early to know where 180’s NAV and the net assets of our SMA will end up as of the end of Q2 2021 or the end of 2021.”

    The table below summarizes 180’s performance over periods of time through the end of Q1 2021:
