This issue of ECS Transactions contain the most recent developments in compound semiconductors encompassing advanced devices, materials growth, characterization, processing, device fabrication, reliability, and other related topics, as well as the most recent developments in processes at the semiconductor/solution interface including etching, oxidation, passivation, film growth, electrochemical and photoelectrochemical processes, electroluminescence, photoluminescence, and other related topics.

This volume contains papers from two symposia: State of the Art Program on Compound Semiconductors 45 and Wide Bandgap Semiconductor Materials and Devices VII.

Section 1 addresses the most recent developments in processes at the semiconductor-solution interface include etching, oxidation, passivation, film growth, porous semiconductor formation, electrochemical, photoelectrochemical, electroluminescence and photoluminescence processes, electroanalytical measurements and related topics on both elemental and compound semiconductors. Section 2 addresses the most recent developments in compound semiconductors encompassing advanced devices, materials growth, characterization, processing, device fabrication, reliability, and related topics.
