Optically Detected Cyclotron Resonance in AgBr

Abstract

Abstract Optically detected magnetic resonance (ODMR) studies reveal cyclotron resonance of electrons and holes in AgBr as well as a number of paramagnetic resonances already observed by other workers. Cyclotron resonance signals are observed in the recombination radiation from excitons bound to iodine isoelectronic impurities. Asymmetry of the electron‐cyclotron resonance gives a measure of the nonparabolicity of the conduction band which results in an energy dependent effective mass. The enhanced trapping of electrons on iodine centres by interaction with LO phonons is discussed.
