This book from MRS dedicated to III-Nitrides, focuses on developments in AlN, GaN, InN and their alloys that are now finding application in short-wavelength lasers ( 400nm, cw at room temperature) and high-power electronics (2.8W/mm at GHz). Experts from fields including crystal growth, condensed matter theory, source chemistry, device processing and device design come together in the volume to address issues of both scientific and technological relevance. And while much of the book reports on advances in material preparation and the understanding of defect issues, similar advances in...

Since the early 1990s when highly efficient gallium nitride blue and ultraviolet LEDs and laser diodes were first demonstrated, the world market for such devices has rapidly expanded. Based on its outstanding properties, including a wide energy band gap, high thermal conductivity, and high electron drift velocity, GaN is uniquely suited for many novel devices including solar-blind UV light detectors, high power microwave transistors, and cold cathode electron emitters.

The widening range of applications are generating an 80% p.a. growth in R&D. This book covers the basic physical...
