Low temperature operation is being studied for electronic circuits and systems to improve speed, reduce noise and increase reliability. Reduced temperature operation results in improved performance from material related properties such as increased thermal and electrical conductivity and increased carrier mobility.

Electron Temperature Gradient Turbulence
Physical Review Letters, 2000The first toroidal, gyrokinetic, electromagnetic simulations of small scale plasma turbulence are presented. The turbulence considered is driven by gradients in the electron temperature. It is found that electron temperature gradient (ETG) turbulence can induce experimentally relevant thermal losses in magnetic confinement fusion devices.

LOW TEMPERATURE ELECTRON MICROSCOPY
Annual Review of Biophysics and Bioengineering, 1981In the investigation of biological ultrastructure by electron microscopy the most significant observation to date is a 1 nm repeat in the purple membrane of Halobacterium halobium (73). With a high degree of certainty, the spacing can be ascribed to the inter a-helical separation within bacteriorhodopsin molecules.

Extreme temperature electronics
2004 IEEE Aerospace Conference Proceedings (IEEE Cat. No.04TH8720), 2004In this paper a new class of electronic devices, called solid state vacuum devices (SSVDs), is presented and discussed with the primary focus aimed toward extreme environment applications. SSVDs, due to their intrinsic high temperature operation and radiation hardness, should be extremely well suited for extreme environments that exist both on Earth ...

Proceedings of the IRE, 1954
Considering potential practical applications of low-temperature phenomena, a general survey is made of the temperature dependence of noise and electrical resistance down to the region of Absolute Zero. It is shown that the signal-to-noise ratio in a metallic resistor can be increased by lowering its temperature, while cooling has little effect on ...

IEEE Circuits and Devices Magazine, 1990
An overview of semiconductor-based and superconductor-based low-temperature electronics is presented. The general issues of reliability and thermal expansion mismatch are discussed. The discussion of semiconductor electronics starts with a description of a cryogenic supercomputer, the ETA, and then covers devices and materials, noise and applications ...

Electron temperature gradient driven turbulence
Physics of Plasmas, 2000Collisionless electron-temperature-gradient-driven (ETG) turbulence in toroidal geometry is studied via nonlinear numerical simulations. To this aim, two massively parallel, fully gyrokinetic Vlasov codes are used, both including electromagnetic effects.

Temperatures of Nuclei, Electron Temperatures and Electron Concentrations
1970The nuclei of planetary nebulae are very hot stars. This fact explains in the first place the large apparent brightness of the nebulae, which are many times brighter than their nuclei. Since the emission of the nebula is caused by short-wave radiation from the nucleus, it follows that the nucleus radiates very much more energy in this region of the ...

ECE imaging of electron temperature and electron temperature fluctuations (invited)
Review of Scientific Instruments, 2001Electron cyclotron emission imaging (ECE imaging or ECEI) is a novel plasma diagnostic technique for the study of electron temperature profiles and fluctuations in magnetic fusion plasma devices. Instead of a single receiver located in the tokamak midplane as in conventional ECE radiometers, ECEI systems utilize large diameter imaging optics coupled ...
