Critical Reviews in Solid State and Materials Sciences, 1999
The factors affecting the feasibility of cryogenically cooled CMOS are reviewed. This approach becomes more attractive as CMOS feature sizes shrink below 250 nm where chip performance is limited by interconnect characteristics. The impact of interconnects is demonstrated using a methodology for estimating interconnect-limited CMOS performance.

Cooling power of transverse thermoelectrics for cryogenic cooling
SPIE Proceedings, 2016Transverse Peltier coolers have been experimentally and theoretically studied since 1960s due to their capability of achieving cooling in a single-leg geometry. Recently proposed p x n -type transverse thermoelectrics reveal the possibility of intrinsic or undoped transverse coolers that can, in principle, function at cryogenic temperatures, which has

Cryogenic Cooling by Noncondensible-Gas Injection
Science, 1965Temperature control of various cryogenic liquids in the range from their boiling points to near or below their freezing points has been achieved by injecting a noncondensing gas, helium. The process is more easily accomplished than the usual vapor-pumping technique and is applicable in the range from 15° to 300°K.

A Cryogenically Cooled Radiometer for 900GHz
16th European Microwave Conference, 1986, 1986A cooled Schottky barrier diode heterodyne receiver has been constructed for operation at 900GHz. A corner cube mixer and a miniature closed cycle cooler were used. The double sideband receiver noise temperature at 890GHz was 15300K, with corresponding Tmxr = 7700K and Lmxr = 18.0dB, and operating under LO-starved conditions.

Effect of cryogenic cooling in milling process of AISI 304 stainless steel
Transactions of Nonferrous Metals Society of China, 2011 The effects of cryogenic cooling on cutting forces in the milling process of AISI 304 stainless steel were investigated experimentally. Cryogenic cooling was achieved by spraying liquid nitrogen to tool, chips and material interfaces using a pipe with an

Cryogenically cooled Er:YAG laser
2007 European Conference on Lasers and Electro-Optics and the International Quantum Electronics Conference, 2007We demonstrated highly efficient ultra-low-photon-defect resonantly diode-pumped Er-doped cryo-cooled laser. Slope efficiency of 71.5% per cavity absorbed power was achieved at 78 degK in these initial experiments. It was shown that cryo-laser resonantly pumped by "full-width" laser diodes can be temperature tuned to achieve better optimized overall ...

A cryogenic-solid cooling system
Infrared Physics, 1964Abstract A theoretical study of a simple and reliable technique for cooling small components to cryogenic temperatures has been concluded. This study indicated that cooling produced by the sublimation of solids is feasible and particularly well suited for long-term use in the space environment.

Spot-Cooling with a Cryogenic Pump
1964Many cryogenic designs have recently been proposed to provide cooling down to 150°K. The conventional methods listed below have many faults when used for “spot-cooling”: 1. Dip-type cooling: This is the simplest method of cooling, which involves submerging the object to be cooled in a bath of coolant.

Cooling by a cryogenic helium system
Chemical and Petroleum Engineering, 1990Cryogenic He systems (CHS) perform two functions: produce a cryogenic agent with given parameters and withdraw heat from the object cooled to the given temperature. Three stages of the CHS operation are recognized: cooling, cyrostatic processing, and heating. The proportion of the cooling stage in the overall CHS balance is comparable to the two others
