Wide Bandgap Semiconductor Devices and MMICs: A DARPA Perspective
This paper reports on the recent successful completion of Phase I of DARPA’s Wide Bandgap Semiconductor Technology Initiative (WBGSTI). Phase I results are given for semi-insulating substrates and epitaxial growth, and a description and expectations for the upcoming Phases II and III are also provided. INTRODUCTION Wide bandgap devices and MMICs with high power density, high power added efficie...
متن کاملWide Bandgap Composite EBG Substrates
High-K ceramics are embedded into a polymer host to create an electromagnetic bandgap (EBG) substrate that possess superior properties to previous bandgap implementations in terms of stopband width, attenuation per layer, and practicality. Ceramics are periodically spaced in a commercially-available, Teflon-based host to create a bandgap that spans from 12.1 to 24.1 GHz. Miniature dielectric ro...
متن کاملWide Bandgap GaN Smart Power Chip Technology
Smart power chip technology has been realized on the GaN-on-Si platform, featuring monolithically integrated power devices, digital and analog functional blocks. In particular, this paper presents the imperative analog functional block – the voltage reference generator for smart power applications with wide-temperature-range stability. These circuits are shown to be capable of proper functions ...
متن کاملWide Bandgap Heterojunctions on Crystalline Silicon
We describe the use of organic and metal oxide semiconductors to form wide-bandgap heterojunctions to crystalline silicon. We use these semiconductors to demonstrate a heterojunction which both blocks electrons and passes holes, and a complementary heterojunction which blocks holes and passes electrons and blocks holes. The carrier transport functions are demonstrated through simple device stru...
متن کاملUltrafast Spectroscopy of Wide Bandgap Semiconductor Nanostructures
Group III-nitrides have been considered a promising choice for the realization of optoelectronic devices since 1970. Since the first demonstration of the high-brightness blue lightemitting diodes (LEDs) by Shuji Nakamura and coworkers, the fabrication of highly efficient white LEDs has passed successful developments. A serious physical issue still remained, which prevents their use for high pow...
