Title: **Howard Lessoff: Innovator in Superconductors and Semiconductors**
Introduction
Howard Lessoff, located in Potomac, Maryland, has made significant contributions to the fields of superconductors and semiconductors. With three patents to his name, Lessoff's innovative works reflect his commitment to advancing technology through meticulous research and development.
Latest Patents
One of Lessoff's notable inventions is a **Method for Growing Patterned Thin Films of Superconductors**. This method involves creating a patterned superconductive oxide film represented by the general formula XZ₂Cu₃O₆+x, where X is yttrium, a lanthanide, or a mixture thereof, Z comprises one or more alkaline earth elements, and x is defined between 0 and 1. The process is accomplished by preparing an aqueous solution of the nitrates of X, Z, and Cu in a specific stoichiometric ratio, followed by spraying it onto a heated substrate to develop a thin film. Controlled heating allows for the transformation of selected portions into a superconductive oxide film, while unheated material is removed with a solvent.
Another of his recent patents is a **Multi-color Tunable Semiconductor Device**. This innovative device operates through multiple epitaxial layers, each with varying compositions. It utilizes a direct current (DC) sweep voltage to deplete the layers sequentially, while an alternating current (AC) voltage modulates the absorption edge of these layers. A variation of this device serves as a variable bandwidth detector, where the spectral bandwidth changes according to the applied DC voltage.
