A novel transit-time device structure for lownoise RF power generation at high millimeter-wave and submillimeter-wave frequencies is proposed. It takes advantage of the unique tunneling properties in strained AlGaN/GaN heterojunctions. The device simulations take realistic heat management for continuous-wave operation on diamond heat sinks into account and, as initial results, predict tunabilit...

The aim of this work is to present a methodology to develop cost-effective thermal management solutions for microelectronic devices, capable of removing maximum amount of heat and delivering maximally uniform surface temperature distributions. The topological and geometrical characteristics of multiple-story threedimensional branching networks of microchannels were developed using multi-objecti...

This article utilizes the experimental method to investigate the thermal performance of heat sinks with one and two pairs of embedded heat pipes. A heat sink with embedded heat pipes transfers the total heat capacity from the heat source to both the base plate and heat pipes, and then disperses heat into the surrounding air via the forced convection. The heat transference from base plate to fin...
