The United States needs a revolution in energy technology innovation to meet the profound economic, environmental, and national security challenges that energy poses in the 21st century. If the U.S. government does not act now to improve the conditions for innovation in energy, even in times of budget strin-gency, it risks losing leadership in one of the(More)
The observation of vanishing electrical resistance in condensed matter has led to the discovery of new phenomena such as, for example, superconductivity, where a zero-resistance state can be detected in a metal below a transition temperature T(c) (ref. 1). More recently, quantum Hall effects were discovered from investigations of zero-resistance states at(More)
We thank all the participants from government, industry, finance and academia who dedicated a substantial amount of time to the topic and the workshop (see Appendix A). We are especially grateful to for taking on the important task of moderating the workshop discussions. Several individuals and organizations contributed to the research through interviews as(More)

Catalytic growth of GaN nanowires by hydride vapour phase epitaxy is demonstrated. Nickel-gold was used as a catalyst. Nanowire growth was limited to areas patterned with catalyst. Characterization of the nanowires with transmission electron microscopy, x-ray diffraction, and low temperature photoluminescence shows that the nanowires are stoichiometric(More)
This paper describes a strategy for the fabrication of functional electronic components (transistors, capacitors, resistors, conductors, and logic gates but not, at present, inductors) that combines a single layer of lithography with angle-dependent physical vapor deposition; this approach is named topographically encoded microlithography (abbreviated as(More)
Our Center develops tools to study nanoscale systems. We would like to control electrons and photons inside nanostructures for new nanoelectronic and nanophotonic devices, and to investigate how biological systems function at the nanoscale using techniques from the Physical Sciences. Three Research Clusters address these goals: Cluster 1: Tools for(More)
