Title: Åke Öberg: Innovator in Photoconductive Technology
Introduction
Åke Öberg is a notable inventor based in Uppsala, Sweden. He has made significant contributions to the field of photoconductive technology, holding a total of 2 patents. His work focuses on innovative devices that utilize light to control electrical currents.
Latest Patents
One of his latest patents is a photoconductive switch. This device comprises a first layer, along with two contact layers arranged on said first layer. These contact layers are connectable to different potentials for applying 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 state that blocks the transport of charge carriers. The first layer is made of intrinsic diamond, while a second layer is arranged next to it. The device operates by providing free charge carriers in the second layer, allowing transport through the diamond layer when a voltage is applied. In the blocking state, the supply of free charge carriers is halted, allowing the diamond layer to take on a major part of the voltage across the terminals.
