Abstract
Emission from individual InAs quantum dots by tunneling current inject ion using a scanning tunneling microscope (STM) is reported. By scanni ng the STM tip above the self-assembled InAs quantum dot structures, a spatially resolved scanning tunneling luminescence (STL) image was me asured, which contained some peaks originating from InAs quantum dots. The width of these peaks are of the same size as the average dot size , suggesting that the resolution of this method is much higher than 20 nm. (C) 1998 Published by Elsevier Science Ltd.
