ABSTRACT:
A method for obtaining increased flexibility and responsiveness in solid state switching devices to effect a change in voltage or field and a corresponding switching device for obtaining such result, wherein the charge transport component of the photoactivated switch is functionally separate and distinct from the photoconductive charge-generating component, the former being initially selected to provide the necessary changes with respect to voltage or field while simultaneously maintaining constant photoconductive parameters such as dark decay, spectral range, etc. in the latter component.
