Extensive simulation experiments are carried out for the first time, to study the photo-irradiation effects on the high frequency characteristics of III-V GaN (Gallium Nitride) based Top-Mounted and Flip-Chip IMPATT oscillators at MM-wave window frequency (140.0 GHz). MM-wave properties of un-illuminated GaN IMPATTs are compared with those of conventional Si, GaAs and InP IMPATTs, under similar operating...
Reliability of terahertz-frequency (~1.0 THz) characteristics of wide-bandgap (WBG) wurtzite (Wz)-GaN- and 4H-SiC-based p++nn++-type single-drift-region (SDR) impact avalanche transit time (IMPATT) devices (normal and photoilluminated) is compared through a simulation scheme. The simulation experiment reveals that an RF power density of 3.37 times 1011 W middotm-2 (efficiency of 18.2%) at around 1...
Terahertz characteristics of opto-sensitive InP based double drift IMPATT diode with and without optical radiation are studied and the results are compared with another opto sensitive semiconductor 4H-SiC based IMPATT at same operating frequency (0.5 THz) . The effects of parasitic series resistance on the THz frequency performance of the simulated InP based diode is also analysed. Unilluminated IMPATT...
