Title: Lloyd Douglas Bell: Innovator in Semiconductor Technology
Introduction
Lloyd Douglas Bell is a notable inventor based in Sunland, California. He has made significant contributions to the field of semiconductor technology, holding a total of 2 patents. His work focuses on enhancing the performance of photodetectors and semiconductor devices.
Latest Patents
One of his latest patents is titled "Piezoelectrically Enhanced Photocathode." This invention involves a photocathode designed to generate electrons in response to incident photons. It features a base layer with a first lattice structure and an active layer with a second lattice structure, which are epitaxially formed on the base layer. The difference in lattice structures creates a strain in the active layer, resulting in a piezoelectrically induced polarization field. The active layer is engineered to have a band gap energy that corresponds to a desired photon energy.
Another significant patent is the "Method for Fabricating Semiconductor Devices." This process allows for the fabrication of gold/gallium arsenide structures in situ on molecular beam epitaxially grown gallium arsenide. The resulting interface is Ohmic, which is an unexpected outcome attributed to increased electrode interdiffusion. This invention enables the creation of Ohmic contacts in III-V semiconductor materials at room temperature, significantly simplifying the fabrication process.
