Title: Mark Irwin: Innovator in Photoconductive Technology
Introduction
Mark Irwin is a notable inventor based in Västerås, Sweden. He has made significant contributions to the field of photoconductive technology, holding a total of 3 patents. His work focuses on innovative devices that utilize light to control electrical currents.
Latest Patents
One of Mark Irwin's latest patents is a photoconductive switch. This device comprises a first layer, along with two contact layers that are arranged on the first layer. These contact layers can be connected to different potentials to apply a voltage across them. The first layer is designed to conduct electricity when exposed to light from an illumination source, such as an excimer lamp. This lamp generates unstable electronically excited dimers that decompose into gas atoms while emitting photons. These photons have sufficient energy to lift charge carriers from the valence band to the conduction band of the first layer's material.
Another significant patent is a switching device that features two opposite terminals interconnected by material layers. This device can switch between a current-conducting state and a blocking state for charge carriers when a voltage is applied. The material layers include a first layer made of intrinsic diamond and a second layer adjacent to it. The device operates by providing free charge carriers in the second layer, allowing transport through the diamond layer when in the conducting state. In the blocking state, the device stops providing free charge carriers, with the diamond layer taking on most of the voltage across the terminals.
