Compact SPICE model for TeraFET resonant detectors
Xueqing Liu, Yuhui Zhang, Trond Ytterdal +1
This paper presents an improved compact model for TeraFETs employing a nonlinear transmission line approach to describe the non-uniform carrier density oscillations and electron in…
Dynamic characteristics of terahertz hot-electron graphene FET bolometers: effect of electron cooling in channel and at side contacts
V. Ryzhii, C. Tang, T. Otsuji +3
We analyze the operation of the hot-electron FET bolometers with the graphene channels (GCs) and the gate barrier layers (BLs). Such bolometers use the thermionic emission of the h…
Terahertz plasmonic resonances in coplanar graphene nanoribbon structures
V. Ryzhii, C. Tang, T. Otsuji +2
We analyze plasmonic oscillations in the coplanar graphene nanoribbon (GNR) structures induced by the applied terahertz (THz) signals and calculate the GNR impedance. The plasmonic…
Quantum Channel AlGaN/GaN/AlGaN High Electron Mobility Transistor
G. Simin, M. Shur
Scaling down the GaN channel in a double heterostructure AlGaN/GaN/AlGaN High Electron Mobility Transistor (HEMT) to the thicknesses on the order of or even smaller than the Bohr r…
Terahertz bolometric detectors based on graphene field-effect transistors with the composite h-BN/black-P/h-BN gate layers using plasmonic resonances
M. Ryzhii, V. Ryzhii, M. S. Shur +3
We propose and analyze the performance of terahertz (THz) room-temperature bolometric detectors based on the graphene channel field-effect transistors (GC-FET). These detectors com…
Resonant THz detection by periodic multi-gate plasmonic FETs
Yuhui Zhang, Michael S. Shur
We show that a periodic multi-grated-gate structure can be applied to THz plasmonic FETs (TeraFETs) to improve the THz detection sensitivity. The introduction of spatial non-unifor…
