Abstract :
The first observations of multiple negative differential resistance (NDR) regions in resonant interband tunneling devices are reported. In vertically integrated poly-type heterostructures of InAs/AlSb/GaSb, the peak voltages are reduced by a factor of 2 compared to the AlInAs/GaInAs material system, while high peak-to-valley ratios of 4:1 (17:1) at 300 K (77 K) are maintained. The InAs/AlSb/GaSb material system offers advantages for circuit applications of such devices, particularly operation at lower voltages.<>
