SEMICONDUCTOR QUANTUM-WELL HETEROSTRUCTURES

Activities in semiconductor heterostructures are reviewed, with focus on the fundamental physics aspects in the quantum regime and with emphasis on recent experimental observations. The GaAs-GaAlAs is used to illustrate the general electronic properties of interest, which are obtained through various measurement techniques. Other heterostructures, including III-V, II(IV)-VI, and IV materials, are covered to the extent that they exhibit new and specific features.
