The goal of this effort is to grow n and p ZnO thin films by MOCVD on ZnO substrates. The primary objective of this phase I effort will be to grow p-n homojucntion and characterize the LED structure. Bandgap of ZnO will be engineered and heterojunction quantum wells will be grown. The grown device structures will be characterized for structure and quality by X-ray, PL and electron microscopy, The ...

The goal of this program is to develop ZnO based light emitters fabricated on high quality ZnO bulk substrates. The work will focus on enhance doping of the active layers, target alloy concentrations and prototype emitter fabrication.

An increasing amount of information comes in the form of streaming text: news media, email, and even human conversation. Creating insight from streaming text has been challenging though, because current knowledge discovery systems depend on expert analysts to move from simple data to actionable knowledge. In order for such systems to be used outside a small cadre of experts, they must incorporat ...

Crossfield proposes to develop a hybrid direct write technique for developing conformal circuits and semiconductors. Crossfield, together with Honeywell and the Massachusetts Institute of Technology (MIT) intend to demonstrate a conformal circuit technique that enables the metal elements of the circuit (such as power and signal traces or antennas) and supporting semiconductors such as bias circui ...

Crossfield proposes a high dynamic range, ultra-wideband, receiver-digitizer that will enable implementation of a compact UWB target identification system for the detection and location of targets and weapons concealed behind walls or foliage or hidden on a person. The design features an ultra-wide bandwidth, high dynamic range sampler developed by Picosecond Pulse Labs, followed by a track-and-ho ...

Crossfield Technology proposes an innovative direct conversion receiver and digital signal processor system that provides ultra wideband frequency coverage at ultra high frequency resolution. Key features of Crossfield's ultra wide band receiver and signal processor design include: Ultra wide band direct conversion (zero-IF or near-zero-IF) using state-of-the-art SiGe analog-to-digital convert ...

A WNW Host Simulator (WHS) can be considered an indoor open-air range in which a JTRS radio is given the various electronic stimuli it needs to 'think' it is in flight operation over a geographic area. The JTR Set and its waveforms are then 'operated' in simulated conditions and its performance and integration with the host platform measured. The goal is to reduce the risk to flight testing by ens ...

The use of oscillatory jet active flow control offers the opportunity to dramatically reduce the parasitic drag of helicopter fueslages and their mission equipment without compromise of utility. A new class of actuator, flight qualification of actuators, and an integrated electronic driver and controller will make possible an efficient full-scale installation and flight test.

Development of actuators is the key to effective AFC! This has been stated in numerous papers and the subject of several programs. This program will produce an environmentally hardened Oscillatory Jet (OJ) Active Flow Control (AFC)system including compact lightweight integrated power electronics, powerful voice-coil actuators, flow separation sensing, and closed loop control. An existing 1/10th ...

Echo Technical and the Ellington Lab at the University of Texas at Austin previously developed a demonstration biosensor capable of using aptamer-based receptors (Biological Reconfigurable Interface Electronics For Classification and Analysis of Selected Elements, or BRIEFCASE). They proposed in Phase I to adapt a recently developed technology, proximity ligation assays, to a field-deployable dev ...
