Abstract
Planar-type self-assembled quantum dots (SAQD) devices were fabricated by depositing Al metal electrodes on an InAs SAQD wafer. The current-voltage characteristics of the SAQD devices exhibited negative differential resistance (NDR) effects above 77 K. This NDR effects were due to the three-dimensional-zero-dimensional resonant tunneling.
