Photothermal Investigations of GaAs-Based Materials and Quantum-Well Structures.

Abstract

Photothermal deflection spectroscopy has been applied to GaAs samples with the ultimate goal of measuring the optoelectronic and thermal transport properties of GaAs based multiple quantum wells by this technique. Theoretical models have been developed as well as experimental investigations have been carried out. Both pulsed as well as cw (modulated) excitations have been considered.
