Abstract: Disclosed herein are methods and mid-IR detection apparatus to measure analytes in gas or liquid phase. Solid state cooling of a crystalline lattice is effectively achieved with the controlled flow of charge carriers that absorb thermal energy from the semiconductor material which senses mid-IR photons. Reduction in temperature improves signal-to-noise ratios thus improving molecular sensitivity. In one embodiment the apparatus is used to detect a biomarker.

Abstract: A high power electronic device package constructed to include a high power electronic device having an epitaxial surface attached to a thermally conductive submount by a thermally conductive interface layer having a eutectic metal contact therein. A gallium nitride high electron mobility transistor (GaN HEMT) having a transistor structure formed of a GaN thin film layer bonded to a thermally conductive host substrate via a thermally conductive interface layer disposed therebetween, and a method of forming the GaN HEMT. The GaN HEMTs can be used in such applications as, for example, power amplifiers with x-band radio frequency (RF) power outputs for micro-radar applications.

The hydrophilic surface sufficiently attracts water molecules within the dishwasher to enhance the drying capabilities of the dishwasher.

Abstract: A semiconductor laser device, and method for making such, having higher operating temperatures than previously available. A semiconductor epitaxial layer is bonding to a cleaving assembly which allows the epitaxial layer to be manipulated without use of traditional substrate forms. The resulting semiconductor laser is bonded to a metal portion which serves as a heat sink for dissipating heat from the active lasing region. The resulting semiconductor lasers can be cooled by thermoelectric cooling modules, thus eliminating the necessity of using more bulky cryogenic systems.
