Project Summary: Two-dimensional transition metal dichalcogenides such as MoS2 have created avenues for exciting physics with unique electronic and photonic applications.
Bayesian networks (BNs) find widespread application in many real-world probabilistic problems including diagnostics, forecasting, computer vision, etc. The basic computing primitive for the implementation of BNs through stochastic computing is a stochastic bit (s-bit) generator that can control the probability of obtaining ‘1’ in a binary bit-stream.
With the emergence of the internet of things, the risk of information loss or security threat heightens. Conventional software crypto modules are powerful, but consume an enormous amount of energy, necessitating innovation in materials, devices, and architectures to produce next-generation secure low-energy electronics.
Project Summary: Materials composed of nitrogen-doped carbon are useful as catalyst supports due to their low cost, low density, and enhanced metal−support interaction. One way to synthesize catalytic single atoms and nuclei on these supports is via vapor phase deposition processes.
Project summary: The electronic and optical properties of 2D materials can be strongly influenced by defects, some of which can find significant implementations, such as controllable doping, prolonged valley lifetime, and single-photon emissions.
Project summary: Transition metal dichalcogenides (TMDs) are seen as potential candidates for complementary metal oxide semiconductor (CMOS) technology in future nodes.
Project Summary: Magnetism in quantum materials creates a fertile ground for the exploration of fundamental spin-based phenomena, with applications in spintronics, magnetic memory, and quantum information technology. This is exemplified by the recent development of magnetic topological materials.
Project Summary: Common metals bounce incident light in the infrared range. In our recent experiments, we discovered that a special class of metals, so called nodal metals hosting the two-dimensional electronic structure with van Hove singularities, support waveguiding of infrared energy in their bulk. This novel plasmonic effects is observed over an extended frequency range in near infrared.
Project Summary: The ability to engineer potential profiles of multilayered materials is critical for designing high-performance tunneling devices such as ferroelectric tunnel junctions (FTJs). FTJs promise electrically switchable memories, sensors, and logic devices.
Project Summary: The emergence of magnetism via a magnetic proximity effect (MPE) allows the realization of magnetic properties in non-magnetic materials, leading to properties not observed in the bulk nor achievable via magnetic doping. MPEs are of particularly significant interest in heterostructures that interface a topological insulator with a ferromagnet.
