The research proposed here is built on the recent successful fabrication of metal oxide semiconductor heterjunction field effect transistors (MOS-HFETs) based on AlGaN/GaN heterostructures with very high drain-current-driving and gate-control capabilitiesas well as unprecedented high breakdown voltages by the P.I.s research group at Kansas State University. III-nitride HFETs have great promises i ...

A cellular neural network (CNN) technology based adaptive multi-target track-ing and discrimination system with compact cellular visual microprocessor is pro-posed.Methodology: The primary motivation of the present proposal is to offer a to-pographic microprocessor architecture for multi-target discrimination with embedded sensors capable of operating in a process real-time manner. The performance ...

FEPET, Inc. has developed a Carbon Nanotube (CNT) cold-cathode material. It has demonstrated the use as an electron beam source in configurations that include both single-beam and arrays of beams. This document reviews the feasibility of development of aCNT-based microwave power amplifier array element and proposes fabricating two elements of a Printed TWT device to demonstrate the viability of ...

InAs/InGaSb type-II superlattices have advantages over HgCdTe for photodetectors requiring higher temperature and longer wavelength operation. The type-II QW photodiodes have comparable quantum efficiency, smaller dark current due to a larger effectivemass, much slower Auger recombination rates, and hence much longer carrier lifetimes. Through careful bandgapengineering, we have suppressed the A ...

A compact mid-IR dual wavelength laser is highly' desirable for the environmental gas and pollutant sensing, such as differential absorption lidar, where the light scattering has to be evaluated and compared at two different wavelengths. In the phase-Iproject, we have demonstrated the first two-color type-II interband-cascade (IC) laser in the world. It shows two lasing wavelengths at 4.482 and 4. ...

Proposed missile defense systems must guard against advanced ballistic and cruise missiles that fly with high velocities and are equipped with their own defense mechanisms. Likely, a successful missile defense system will employ both kinetic killtechnologies as well as High Power Microwave (HPM) and RF weapon systems. Typical HPM and RF weapon technologies are mired by their excessive volumes an ...

This Small Business Innovation Research (SBIR) Phase II project will fabricate a prototype betavoltaic battery in a form factor the size of a quarter coin. The goal will be to generate approximately 100 microwatts of electrical power in a volume less than half a cubic centimeter from a tritiated energy source. Research conducted for the Phase I portion of this project established the feasibility o ...

This Small Business Innovation Research (SBIR) Phase II project will develop a ceramic hydrogen fuel appliance (CHFA) using ceramic microreactor modules (CMMs) using a low-cost, net-shape manufacturing process, and a new material, that was developed in the Phase I project. The new material developed was demonstrated to have excellent capability for cost-effective microfabri ...
