0.52eV Quaternary InGaAsSb Thermophotovoltaic Diode Technology

Thermophotovoltaic (TPV) diodes fabricated from 0.52eV lattice-matched InGaAsSb alloys are grown by Metal Organic Vapor Phase Epitaxy (MOVPE) on GaSb substrates. 4cm{sup 2} multi-chip diode modules with front-surface spectral filters were tested in a vacuum cavity and attained measured efficiency and power density of 19% and 0.58 W/cm{sup 2} respectively at operating at temperatures of T{sub radiator} = 950 C and T{sub diode} = 27 C. Device modeling and minority carrier lifetime measurements of double heterostructure lifetime specimens indicate that diode conversion efficiency is limited predominantly by interface recombination and photon energy loss to the GaSb substrate and back ohmic contact. Recent improvements to the diode include lattice-matched p-type AlGaAsSb passivating layers with interface recombination velocities less than 100 cm/s and new processing techniques enabling thinned substrates and back surface reflectors. Modeling predictions of these improvements to the diode architecture indicate that conversion efficiencies from 27-30% and {approx}0.85 W/cm{sup 2} could be attained under the above operating temperatures.

2005 AF Base Realignment and Closure (BRAC 2005) Site Survey Guidance

SAF/IEB will oversee a series ofMAJCOM directed site surveys for bases affected by BRAC 2005 recommendations. These site surveys are the first step in identifying BRAC 2005 operational, communications and construction requirements for use in future programming actions. Attached is the installation site survey priority list (Atch I).

2005 BRAC Implementation Guidance

The analysis phase of the BRAC 2005 effort is coming to a close. It is time to consider implementation guidance and how it affects you. Initial guidance is being prepared to help you during preliminary BRAC implementation planning. The basic preparation for closure or realignment is similar to what bases and MAJCOMs went through during the last four BRAC rounds. Details might differ but the end result will be the same.
