The low detectivity of VPD-PbSe MIR detectors was broken by duplicating the microstructural features and phase composition of high-performance CBD-PbSe detectors, providing a commercial technical solution for megapixel uncooled PbSe FPA imagers.

The ever-growing interest in nanocoating and its enthralling protective properties makes it a very capable candidate for next generation protecting systems. The future of these special nanocoating markets will be expanding in different industries such as marine, building, and defense. The main purpose of coatings involves the use of thin films (nanoscale dimensions) that are applied to the surface of materials, which improve the material functionalities. Some of the improved functionalities include anti-corrosion, easy-to-clean (anti-graffiti), anti-icing, anti-fogging, anti-fouling, etc. Some of the common techniques used for nanocoating are chemical vapor phase deposition, physical vapor phase deposition, Sol-gel methods, electro-spark deposition, electrochemical deposition, and laser beam surface treatment. Commercial application of nanocoating nanotechnology includes self-cleaning coatings, depolluting coatings, ultraviolet (UV) light protective coatings, anticorrosion coatings, thermal resistance, anti-fouling coatings, and anti-graffiti coatings.

We analyze the thermal behavior of a flexible nanowire (NW) light-emitting diode (LED) operated under different injection conditions. The LED is based on metal–organic vapor-phase deposition (MOCVD)-grown self-assembled InGaN/GaN NWs in a polydimethylsiloxane (PDMS) matrix. Despite the poor thermal conductivity of the polymer, active nitride NWs effectively dissipate heat to the substrate. Therefore, the flexible LED mounted on a copper heat sink can operate under high injection without significant overheating, while the device mounted on a plastic holder showed a 25% higher temperature for the same injected current. The efficiency of the heat dissipation by nitride NWs was further confirmed with finite-element modeling of the temperature distribution in a NW/polymer composite membrane.
