Kyma Technologies will develop a cost-effective technique to grow high-quality gallium nitride (GaN) by developing a high growth rate process for creating crystalline GaN boules, which are used as a starting material for semiconductor device manufacturing. Currently, growing boules from GaN seeds is slow, expensive, and inconsistent, which negatively affects manufacturing yield and electronic devi ...

In this program, we will develop a breakthrough technology that will enable wafer-scale epitaxial lift-off (ELO) of GaN power device heterostructures from low-dislocation-density bulk GaN substrates. This technology will be used to provide a low-cost vertical junction field effect transistors (VJFETs) with high breakdown voltage (greater than 1,200 V) and high current capability (greater than 100 ...

SixPoint Materials will create low-cost, high-quality vertical gallium nitride (GaN) substrates using a multi-phase production approach that employs both hydride vapor phase epitaxy (HVPE) technology and ammonothermal growth techniques to lower costs and maintain crystal quality. Substrates are thin wafers of semiconducting material needed for power devices. In its two-phase project, SixPoint Mate ...

Concentrator PV systems using highly efficient multijunction photovoltaic cells hold out the promise of very low-cost solar electricity generation, but their adoption has been hamstrung by the requirement for bulky mechanical trackers that add cost, diminish land use, increase maintenance, and exclude roof-top installations. The Stationary Wide-Angle Concentrator (SWAC) PV system will provides the ...

The team of Mohawk Innovative Technology Inc., (MiTi), University of Texas – Center for Electro-Mechanics and MITIS of Belgium propose a truly transformative, ultra-high-speed and oilfree, Hyperlaminar Flow Engine (HFE) system that combines low cost viscous shear driven compressor and expander, an integrated low pressure drop recuperator, flameless combustor, permanent magnet generator, lubrican ...

We propose a novel high efficiency (≈40%) generator system capable of providing 1 kWe along with hot water on-demand. The integration of two novel concepts: 1) an internal combustion engine (ICE) operating on Spark-Assisted Compression Ignition (SACI) combustion of natural gas (NG), and 2) a bottoming Organic Rankine Cycle (ORC) with waste energy recovery (WER) from ICE exhaust enables the overa ...

The sodium battery using beta-alumina solid electrolyte is one of the most promising grid-scale electrical energy storage technologies that can balance the short-duration variability in renewable generation. Despite many advantages, the sodium batteries have several barriers for successful commercialization, mainly related to safety issues and high capital investment for installation. The safety i ...

GaN-based devices are the basis of a variety of modern electronics applications, especially in optoelectronics and high-frequency / high-power electronics. These devices are based on epitaxial films grown on single-crystal wafers. The single-crystal wafer substrates are limiting because of their size, expense, mechanical properties and availability. If one could make GaN-based devices over large a ...
