STM Investigation of a Strong Electric Field Effect on Local Photocurrent Spectra in InAs/GaAs Quantum Dot Heterostructures

Abstract

We demonstrate a possibility of using scanning tunneling microscope (STM) for a high spatial resolution study of photocurrent spectra of quantum-dimensional structures The effect produced by an electric field on the position and intensity of the size quantization levels maxima in the local photocurrent spectra for InAs/GaAs structures with quantum dots located near the sample surface is investigated.
