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 ...

The DOEs & quot;Monitoring Verification and Accounting (MVA) program goal is to confirm permanent storage of CO2 in geologic formations by real-time monitoring should CO2 leak. Remote technologies, effective for atmospheric or above ground CO2 monitoring, are ineffective for subsurface, and it is where leakage can be detected first. By the time leaked CO2 slowly appears on the surface, CO2 may hav ...

The main focus of this STTR is to design, develop, and evaluate high temperature capacitors using novel thermal spray coating processes, which will allow the devices to meet the performance requirements. Multilayer coating architecture will be adopted and the electrodes and dielectric material selections will be screened in Phase I to note material compatibility and high temperature performance. ...

Statement of Problem: The US DOE has set a goal to advance photovoltaics (PV) technology to reach installed costs of less than $1/Watt. This requires module costs below $0.50/ Watt. Thin film PV provides the lowest documented production cost per watt ($0.67) of any PV technology. Module reliability has a direct impact on the levalized cost of energy (LCOE), or the cost of the energy produced by ...

Improved ignition methods are needed for advanced vehicle combustion systems, in particular those that allow reliable ignition of lean mixtures in gasoline engines at elevated pressures. Laser ignition is a candidate technology having the potential to address these needs. However, despite more than 40 years of laser ignition research, the technology is not yet in commercial use. A critical proble ...

Many important technology challenges today such as the capacity and life time of batteries require new characterization techniques to understand and improve performance. In the STTR Phase II project, novel x-ray microscope techniques and software are developed to be able to image samples in three dimensions and determine chemical composition and function on a microscopic level. As known from ubi ...

Infrared spectroscopy is the most widely used technique for chemical characterization with a worldwide market of over $1B annually. Conventional infrared spectroscopy suffers, however, from fundamental spatial resolution limits that prohibit its application at the nanoscale. This has prevented widespread use of IR spectroscopy in the growing field of nanoscale materials. The atomic force microsc ...

The feasibility for fusion as a practical energy source needs to be enhanced significantly by removing some of the restrictions that low-temperature superconductors put on the fusion magnet systems. This can be done by using high-temperature superconductors, allowing for much larger temperature margins, a higher magnet performance and less mechanical degradation during operation. There are curren ...

Considerable progress has been made in developing promising subsystems for muon beam cooling channels to provide the great reduction of emittances required for an Energy-Frontier Muon Collider; but an end-to-end design is lacking. Meanwhile, the recent discovery of a Higgs-like boson has created interest in the high-energy physics community for a Higgs Factory to investigate whether its propertie ...

Current state-of-the-art SRF accelerating cavities require the use of many complex and expensive techniques throughout their fabrication/performance cycle. This project will utilize a novel Additive Manufacturing (AM) process to produce nearly monolithic SRF niobium cavities of arbitrary shape with features such as optimized wall thickness and/or integrated stiffeners, greatly reducing the cost a ...
