Microwave integrated-circuit-compatible InAs/AlSb resonant tunneling d
iodes (RTD's) have been fabricated. The resulting devices have peak cu
rrent densities of 3.3 x 10(5) A/cm2 with peak-to-valley ratios (PVR's
) of 3.3. Switching transition times of 1.7 ps are measured using elec
tro-optic sampling techniques.
