In Phase II we propose to optimize wafer scale MoS2 deposition process to fabricate uniform large area monolayer and multi-layer MoS2 films and analyze the defects on these films. Monolayer regions that can result in device periphery larger than 50m will be targeted. Further, the charge transfer doping process using TiOx will be optimized for MoS2 multi-layer and RF transistors will be fabrication ...

Clinical monitoring of mental health status has not evolved much from the routine meeting between patient and clinician, which suffers from a lack of quantification, irregular and anecdotal reporting, and does not necessarily include input from family. This is unfortunate given current technology, in which people routinely volunteer to track their own health related behavior, such as exercise and ...

Spontaneous emission is a quantum mechanical process that represents the main source of phase noise in state-of-the-art semiconductor lasers, limiting their coherence, and their suitability for high-speed communication and sensing applications. This proposal aims to develop ultra-high coherence semiconductor lasers on the Silicon/III-V platform with a quantum linewidth of

This proposal addresses the problem of PCSS/laser trigger integration using a single monolithic laser diode array, thus simplifying the entire optical delivery network necessary for efficient operation of PCSSs. The proposal constitutes a logical continuation of Phase I effort where the main focus was on the detailed design of the PCSS/laser diode array (LDA) integrated architecture. In Phase II ...

In Phase I, TRI/Austin teamed with Missouri S&T to investigate and refine several technologies, i.e. synthetic aperture radar (SAR) imaging algorithms; advanced Compressive Sensing (CS) techniques; innovative imaging hardware; under-sampling; etc, as they apply to high speed millimeter wave imaging. These investigations were supported by both modeling and empirical testing. The Phase I results c ...

Americas current electronic warfare (EW) capabilities are insufficient for the modern and future battlefield. In order to safeguard against radio-controlled threats and disrupt enemy communications, our current EW systems blindly jam broad swaths of the electromagnetic spectrum (EMS), an approach that also disrupts GPS and blue force data and voice communications. In order to broadband jam vast a ...

Due to the limited amount of rhenium present in the earths crust (approximately 1-2 part per billion) there is a significant benefit to be realized in recovering for reuse the rhenium from scrap material, spent catalysts, or end-of-life superalloys. Rhenium is found in molybdenum-copper porphyry deposits. If rhenium is present in ore that is processed, it will show up in the resulting molybdenum ...

Empirical-based mathematical framework and computer algorithms, for representing human perception and cognition processes and limitations, which influence the recognition of salient information about rapidly changing events.

The objective of this Phase II proposal is to continue the development of a Photoconductive Semiconductor Switch (PCSS) with an integrated optical trigger that can switch at least 30 kV, 1 kA, 20 ns pulses with jitter 108 shots. Ness Engineering, Inc. (NEI) and Texas Tech University (TTU) propose to utilize wide bandgap materials to demonstrate lock-on switching and allow much less optical trigger ...

In military settings, vehicle engine noise can be a source of vulnerability, revealing the location of vital resources to hostile threats. Cancellation of the vehicles noise is necessary to safeguard many military missions and mitigate enemy threats. This proposal concerns an innovative lightweight thermoacoustic device using thin, flexible, novel materials for active noise cancellation of militar ...
