M. Reddy et al., MONOLITHIC SCHOTTKY-COLLECTOR RESONANT TUNNEL-DIODE OSCILLATOR ARRAYSTO 650 GHZ, IEEE electron device letters, 18(5), 1997, pp. 218-221
We report monolithic array oscillators incorporating Schottky-collecto
r resonant tunnel diodes (SRTD's), In the SRTD, a 0.1-mu m width Schot
tky collector contact provides a greatly reduced device series resista
nce, resulting in an estimated 2.2 THz maximum frequency of oscillatio
n, A 64-element oscillator array oscillated at 650 GHz while a 16-elem
ent array produced 28 mu W at 290 GHz.
