Temperature-Dependent Electrical Characteristics and Low-Frequency Noise Analysis of AlGaN/GaN HEMTs
Publikováno v:
IEEE Journal of the Electron Devices Society, Vol 12, Pp 698-702 (2024)
In this paper, we investigate the electrical characteristics of AlGaN/GaN HEMTs at the lowest temperature of 20 K. The measurement results indicate that the output current of the device decreases significantly with increasing temperature at temperatu

Compared with the globe valves and other on-off valves, cavitation and noise are more severe in the throttle control valve of the refrigerating system due to the higher saturated vapor pressure of the refrigerant. A short tube throttle valve (STTV) i

Abstract We give the first numerical calculation of the spectrum of the Laplacian acting on bundle-valued forms on a Calabi-Yau three-fold. Specifically, we show how to compute the approximate eigenvalues and eigenmodes of the Dolbeault Laplacian act

Abstract The spin-textures of bound medium-body systems with spin- $$\mathfrak {f}$$ f atoms ( $$\mathfrak {f}\ge 3$$ f ≥ 3 ) have been studied. The Hamiltonian is assumed to be dominated by the two-body interaction favoring parallel spins. The sys

Abstract We have found a stable spin-structure of N $$=$$ = 3 system in which three spin-3 atoms are trapped and coupled to total spin S $$=$$ = 3. We have proved that a pair of this structure is nearly an exact solution for N $$=$$ = 6 systems in a
