摘要
We report the first observations of multiple negative differential resistance (NDR) regions in resonant interband tunneling devices. In vertically integrated poly-type heterostructures of InAs/AISb/GaSb, the peak voltages are reduced by a factor of 2 compared to the Alln-As/GalnAs material system, while high peak-to-valley ratios of 4:1 (17:1) at 300 K (77 K) are maintained. © 1990 IEEE
