MOVPE-Grown Quantum Cascade Laser Structures Studied by Kelvin Probe Force Microscopy
A technique for direct study of the distribution of the applied voltage within a quantum cascade laser (QCL) has been developed. The detailed profile of the potential in the laser claddings and laser core region has been obtained by gradient scanning Kelvin probe force microscopy (KPFM) across the c...
