A -- ANTIMONIDE BASED THERMOPHOTOVOLTAIC CELL MATERIALS Contact L. J. Ross - Contract Administrator (518) 395-4567. ANTIMONIDE-BASED TERNARY AND QUATERNARY MATERIALS - KAPL is seeking sources with expertise in the technologies of bulk crystal or epitaxially grown Antimonide-based semiconductor materials which can be developed to achieve the efforts described as follows: (1) Bulk crystal growths of low bandgap (0.4-06eV) InGaAs and InGaSb ternary alloys, (2) Epitaxial growths of low bandgap (0.4-0.6eV), quaternary alloys of InPAsSb and InGaAsSb lattice matched to InAs or GaSb substrates. Growths must be uniform over a minimum area of 1.0 cm2 and shall include various layer dopings and layer thicknesses (typically about six layers) up to approximately 10 microns total growth thickness. In addition, KAPL seeks related information pertaining to epitaxial and bulk crystal material characterization capabilities (for example such things as x-ray diffractometry, Hall Effect measurements, near to mid infrared Spectro-photometry, etc.) and associated facilities for both growth and characterization. This synopsis is for information and planning purposes only and does not constitute a solicitation for bids or proposals and is not to be construed as a commitment by the Government. The Government does not intend to pay for any information provided under this synopsis. Firms possessing the capabilities to achieve these tasks should submit information pertaining to these capabilities. Information supplied shall include as a minimum past experience, identification of existing equipment and facilities, and other data pertaining to the aforementioned requirements. Vendors are invited to submit a written indication of interest, to be postmarked no later than fifteen (15) working days after the date of this announcement to the address above. (130)
