Title: George D. Lawrence: Innovator in Semiconductor Technology
Introduction
George D. Lawrence is a notable inventor based in Los Angeles, CA. He has made significant contributions to the field of semiconductor technology, holding a total of 3 patents. His work has had a lasting impact on the development of optical switches and related devices.
Latest Patents
One of his latest patents is a semiconductor-to-metal optical switch designed for power limitation in the infrared spectral region. This innovative device includes two thin semiconductor layers sandwiched between two transparent electrodes. An electrical voltage is applied across the two semiconductor layers to create an active device that blocks incident light in the 8 to 12 µm spectral region. The material composition and thickness of the semiconductor layers are engineered to generate enough photo-excited electrons in the first layer, allowing the second layer to undergo a rapid semiconductor-to-metal transition at a predetermined light intensity. Below this threshold, the layers remain transparent, while above it, the second layer becomes metal-like and effectively blocks incident light. The first semiconductor layer can be made from materials such as mercury cadmium telluride, while the second can be made from germanium.
