258 \ENCYCLOPEDIA OF ELECTRICAL AND ELECTRONICS ENGINEERING " JOHN WILEY & SONS, INC Charge Injection Devices

Abstract|The name "charge injection " describes the opera-tion of a generic class of electronic and optoelectronic multi-terminal semiconductor devices, based on the real space transfer of hot carriers over a potential barrier into adja-cent and separately contacted layers. Charge injection de-vices enable the implementation of compact optoelectronic gates endowed with a powerful logic functionality
