Shuji Nakamura recently developed the first commercially available blue and green light emitting diodes. Subsequently he demonstrated the first blue semiconductor laser based on GaN. GaN and its related compounds allow the fabrication of highly efficient light emitters and lasers ranging from red through yellow and green to blue in a single material system. In this book the physical concept and basic manufacturing technology of these new blue light emitting diodes and laser diodes are discussed. The breakthrough in GaN technology opens many new commercial applications for semiconductors, comprising displays, road and railway signalling, lighting, scanners, optical data storage, and much more. This book also gives information on the extraordinary realization of an extremely successful concept of research and development through Nakamura's work. The book appeals to researchers as well as to engineers.

Ludwig Boltzmann revolutionierte die Physik des ausgehenden 19. Jahrhunderts. Er kämpfte beharrlich um Anerkennung, dass jede Materie aus Atomen besteht. Darauf aufbauend begründete er seine kinetische Gastheorie und die statistische Thermodynamik und war somit ein wesentlicher Begründer der statistischen Physik. Eine leicht verständliche Darstellung der Bedeutung Boltzmann’s für die Evolution der Physik. Der Reader bietet eine ausführliche persönliche und wissenschaftliche Biographie, beschreibt seinen Kampf um Anerkennung der Atomistik, seine wesentlichen Zeitgenossen und seine Philosophie. Bisher nicht bekannte Texte, Bilder und Dokumente sowie u. a. auch ein vollständiges Werkverzeichnis runden den umfangreich bebilderten Band ab.
