Verilog-A Device Models for Cryogenic Temperature Operation of Bulk Silicon CMOS Devices

These models can be used in cryogenic electronics applications such as cooled imagers and sensors, medical electronics, and remote sensing satellites. Verilog-A based cryogenic bulk CMOS (complementary metal oxide semiconductor) compact models are built for state-ofthe- art silicon CMOS processes. These models accurately predict device operation at cryogenic temperatures down to 4 K. The models are compatible with commercial circuit simulators. The models extend the standard BSIM4 [Berkeley Short-channel IGFET (insulated-gate field-effect transistor ) Model] type compact models by re-parameterizing existing equations, as well as adding new equations that capture the physics of device operation at cryogenic temperatures. These models will allow circuit designers to create optimized, reliable, and robust circuits operating at cryogenic temperatures.

Thermally Resilient, Broadband Optical Absorber From UV to IR Derived From Carbon Nanostructures

This technology can be used in aerospace, semiconductors, antireflection coatings, optoelectronics, and communications. Optical absorber coatings have been developed from carbon-based paints, metal blacks, or glassy carbon. However, such materials are not truly black and have poor absorption characteristics at longer wavelengths. The blackness of such coatings is important to increase the accuracy of calibration targets used in radiometric imaging spectrometers since blackbody cavities are prohibitively large in size. Such coatings are also useful potentially for thermal detectors, where a broadband absorber is desired. Au-black has been a commonly used broadband optical absorber, but it is very fragile and can easily be damaged by heat and mechanical vibration. An optically efficient, thermally rugged absorber could also be beneficial for thermal solar cell applications for energy harnessing, particularly in the 350–2,500 nm spectral window.
