摘要:
A technique for forming from staring precursors at the molecular level, a sultant thermoelectric material with a reduced thermal conductivity. All staring precursors are dissolved in solution, reduced to remove oxygen, and then combined into a single solution to yield specific stoichiometric ratios. A sol and then a gel is formed, which supercritical solvent extraction is performed upon so as to yield a material having two level porosity and a maximum of a factor of three reduction in thermal conductivity.
摘要:
A nanoporous semiconductor material and fabrication technique for use as rmoelectric elements. Starting precursors are mixed in solution so as to thoroughly dissolve in solution which is then reduced. A second phase may be added in solution to provide nanoinclusions which may be subsequently removed. A nanoporous semiconductor is formed whereby lattice thermal conductivity is greatly reduced, due to enhanced phonon scattering on the order of 10 W/cm.multidot..degree.K. The nanoporous semiconductor material may be used as the n- and p- legs in a Peltier couple utilized for a thermoelectric cooler, a cryogenic cooler, thermoelectric power generator, or a thermoelectric heat pump.

An improved infrared detector element and an improved method for manufactng same is provided. A commercially available rough art wafer of ferroelectric material is ion milled under conditions which provide an extremely thin element with a near flawless detection surface.
摘要:
The invention is related to electronic and more specifically to photo-electronic devices manufactured by means of thin film layering techniques. The invention proposes the use of polymer, copolymer, polyamide and similar organic casting materials, in layers 500 to 10,000 angstroms thick, as protective barriers between layers where the processing of one layer would be adversely affected by or would damage an adjacent previously formed layer.
