Title: The Innovative Contributions of John C. Gustafson
Introduction
John C. Gustafson, an accomplished inventor based in Harvard, MA, has made significant strides in the field of semiconductor technology. With a total of five patents to his name, Gustafson’s work exemplifies the intersection of theoretical insight and practical application in electrical engineering.
Latest Patents
Among his latest patents, Gustafson developed a groundbreaking invention titled "Semiconductor Metal Composite Field Emission Cathodes." This innovation features a field emission cathode consisting of a parallel array of individual electrically conductive rods made from metal silicide or germanide, embedded in a silicon-based or germanium-based single crystal matrix. The careful design ensures each rod has an emission end exposed at one major surface and an ohmic contact end exposed at the opposite major surface. A preferred configuration of the cathode employs a eutectic composition of matrix and rod materials, fabricated through a meticulous process involving the production of a composite boule. This foundational structure is then shaped to ensure optimal emission surface exposure, potentially through etching methods to reveal a uniform length of the rods.
Another notable patent involves a "Method of Making Electrical Contacts," which provides a comprehensive approach to preparing electrical contacts and electrical contact materials. This method includes blending a conductive metallic component like silver with nickel and zirconium diboride, free from oxides, and pressing this mixture into a pre-sintered compact. The final process results in liquid phase sintering to create a densified body, enhancing the efficiency and effectiveness of electrical contacts.
