Development of Diamond-Based Materials Systems for High-Power RF Electronics: First-Year Report

Abstract

The report details the first-year research effort that is part of the Cooperative Agreement between Rice University and US Army Combat Capabilities Development Command Army Research Laboratory. The project aims to develop diamond and diamond-based heterostructures for the next generation of ultra-wide-bandgap electronic devices, with performances far exceeding existing diamond devices as well as other wide-bandgap-material-based devices. The Rice team focuses on the growth of high-quality, single-crystal diamond substrates and heterostructures of diamond and boron nitride, and the DEVCOM Army Research Laboratory team is building high-performance electronic devices based on diamond, specifically using transfer doping of hydrogenated diamond surfaces. Rice has established a world-class facility to grow single-crystal diamond and heterostructures. First-year work has included growth and transfer of boron nitride on commercially available diamond substrates, doping using ion implantation, development of unique metrology tools to characterize diamond surfaces, surface modification using hydrogenation and oxygenation, and development of theoretical models to understand the growth and surface characteristics of diamond. The synergy between the two institutions establishes a close working relationship leading to the synthesis of controlled diamond materials and their utilization in high-power devices.
