3. Epitaxy, analysis and application of semi-insulating III-V materials
Abstract : Semi-insulating (SI) III-V materials can provide electricalisolation for integration and capacitance minimisation for highspeed operation. Compared to the polyimides, these can offerbetter thermal conduction. Ever since the fabrication of thefirst SI III-V materials, transition metals have been utilisedas deep impurities to impart SI properties. READ MORE
