摘要
We fabricated and characterized planar quantum dot devices with a single self-assembled quantum dot placed in between two aluminum electrodes separated by 30 nm. The current-voltage characteristics measured from the devices exhibit negative differential resistances at temperatures above 77 K. They are attributed to the 3D-0D-3D resonant tunneling through the InAs self-assembled quantum dot. (C) 1999 Elsevier Science B.V. All rights reserved.
