GHz-THz Electronics

Objective
The focus of the portfolio is on understanding and exploiting fundamental interactions of electrons and quasiparticles with each other and their host materials in all regions of device operation. Technical challenges include understanding and controlling (1) interactions between particles/quasiparticles and the host lattices, boundaries, and defects, including thermal effects and changes over time that limit lifetime and performance; (2) carrier velocity; (3) dielectric properties and electric field distributions within the dielectrics; and (4) new methods of device operation that do not rely solely on conventional transistors or transport mechanisms such as drift, diffusion, and tunneling. Included are carrier transport and properties in regimes in which transport is not limited by scattering mechanisms. Efficiency, volume, and raw speed matter, but other figures of merit, such as speed or energy of computation, are also of interest. A subarea of interest is two-dimensional materials other than graphene as enablers for high-speed electronics, with focus on bandgap engineering and the unique properties of these materials and heterostructures as basic building blocks for new devices. Research into devices based on materials that perform multiple electronic, magnetic, and optical functions is of interest. It is expected that in order to fully understand the various new phenomena and device configurations, novel techniques to study and control nanoscale structures, defects, and operations must be developed. Before developing white papers or full proposals, researchers are highly encouraged to contact the Program Officer to discuss the current state-of-the-art, how the proposed effort would advance it, and the approximate cost for a three- to five-year effort.
