摘要：
The tunneling mechanism responsible for negative differential resistance in GaSb/AlSb/GaSb/AlSb/InAs double-barrier interband tunneling structures was studied systematically. It was found that the peak current results from resonant interband tunneling and that the spacers make a significant contribution to the valley current. Furthermore, the optimal thicknesses for the GaSb well and AlSb barriers were predicted to be 65 angstrom and 10 angstrom, respectively, which agrees fairly well with experimental results. Our theoretical results give some useful design principles for this type of interband tunneling device.
