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 ...

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 ...

We propose to develop reactive composite materials with sufficient strength and stiffness to serve as structural components for penetrating weapons and other munitions. The composites will consist of two materials that react with each other, in either oxidation-reduction (such as in a thermite) or bimetallic reactions. One component will be in the form of fiber, wire, or wire-mesh, within a bondin ...

The need for novel weapons to defeat urban targets and rapidly immobalize enemy combatants hiding in bunkers, caves, and basements requires new weapons and tactics. Thermobaric warheads can provide tailored blast response optimized for the defeat of these targets with low collateral damage. In this Phase I SBIR program, Powdermet will develop surface-coated metallic particles that can deliver tail ...

The US Department of Energy (DOE)s networking cyber infrastructures are experiencing a massive explo- sion of data volumes because of emerging e-science applications to support high-energy physics, astrophysics, genomics, climate modeling, large-scale science collaborations, etc. The same is true for other networks around the world to support smart devices, big data applications, social ne ...

Designing an efficient and scalable network fault diagnose tool for such a complex system is facing the following challenges: 1) Inherently unpredictable and fault-prone status in the involved networks for scientific collaboration and science mission due to the dynamic nature of network and service demands, and the increasing complexity of configuration options resulting from the imp ...

As supercomputing speeds increase and storage costs drop, scientists running applications in various disci- plines, such as high-energy physics, genomics, climate studies, etc., generate datasets of ever-increasing sizes at distributed locations around the world. Backbone Research-and-Education Network (REN) providers such as DOEs Energy Sciences Network (ESnet) and Internet2, provide high-speed, ...

This Small Business Innovation Research proposal presents AutoPHY, an autonomous, virtualized layer 0 interconnection service for data centers and cloud computing. The Open Systems Interconnection (OSI) stack representing the Internet infrastructure consists of layers 0 to 7. Today all layers can be automatically configured and managed through software, with the exception ...

The interconnect networks of datacenters and extreme scale high performance computers (HPC) will require a bandwidth density, in terms of connections per area, that cannot practically be met with todays optical transceiver technology. The push for high-radix connectivity in combination with an ever increasing amount of data transported on these advanced networks requires increasing num ...

This DOE SBIR program would develop a manufacturing process to produce plastic optical fibers with bandwidth, bend loss and ease of installation significantly improved over currently available products. Current polymer optical fibers are manufactured using bulk polymer processing methods. These methods limit the types of fiber waveguides that may be formed, so significantly l ...
