Quasi-Two-Dimensional Phenomena at Aluminum-Gallium - Arsenide - Gallium-Arsenide Heterointerfaces: Multiple Quantum Wells and Modulation-Doped Structures (Superlattice, Modfet, Semiconductors)
This thesis describes a subset of phenomena at AlGaAs-GaAs heterointerfaces related to multiple quantum wells and modulation-doped structures. In the first section, two important results concerning multiple quantum well systems are described: optical absorption coefficients and exciton oscillator …

A Study on the Nature of Anomalous Current Conduction in Gallium Nitride
… surface features, while CAFM spectroscopy on a MODFET structure indicates a correlation between extended defects and field conduction behavior at room temperature. A remedy for poor conduction characteristics is presented in molten KOH etching, as evidenced by CAFM measurements, Schottky diodes, …
