A USE OF A SEMICONDUCTOR DEVICE, A METHOD FOR CONTROLLING THE STATE OF A SEMICONDUCTOR SWITCH AND AN ELECTRICAL ARRANGEMENT

摘要

A semiconductor device having two terminals (1, 2) interconnected by one or more material layers for switching between a state of conducting current and a state of blocking transport of charge carriers between said terminals upon applying a voltage thereacross is used as a switch in electrical applications where high voltages may prevail. It is an optically activated semiconductor device, changing between a conducting and a non-conducting state substantially instantaneously by starting or interrupting illumination of a surface of said device, that is used as said switch.
