This comprehensive book reports on recent investigations of lattice imperfections in semiconductors by means of positron annihilation. It reviews positron techn

The lifetime of a positron inside a solid is normally less than a fraction of nanosecond. This is a very short time on a human scale, but is long enough to enab

Research advances in III-nitride semiconductor materials and device have led to an exponential increase in activity directed towards electronic and optoelectron

In condensed matter initially fast positrons annihilate after having reached equi librium with the surroundings. The interaction of positrons with matter is gov

Understanding the formation and introduction mechanisms of defects in semiconductors is essential to understanding their properties. Although many defect-relate
