Abstract

We have fabricated and characterized the lateral electron transport through InAs quantum dots with double barrier system. Aluminum metal electrodes with the inter-electrode spacing of 30 nm have been deposited on an InAs self-assembled quantum dot wafer to form the planar type quantum dot devices. Current peak structure and negative differential resistance effects are observed above 77 K in current-voltage characteristics. These results are interpreted as due to 3D-OD resonant tunneling through the single quantum dot positioned in between the electrodes.
