Failure analysis of a quantum cascade laser structure by electrostatic force microscopy

Abstract

Noncontact mode electrostatic force microscopy was employed to investigate cleaved sections of a GaSb-based quantum cascade laser structure. The technique enabled us to determine the surface potential distribution, at equilibrium and under applied external field, and to locate precisely the zone which is at the origin of failure in laser characteristics when a breakdown voltage is applied to the device
