Superconducting Electronics at mK Temperatures

Journal of Low Temperature Physics, 2004
The interest in superconducting electronics working at millikelvin temperatures has increased during the past few years, and several novel devices and amplifiers utilizing mesoscopic Josephson junctions have been developed. We review the present status of a few of these devices, foremost the inductively-read superconducting Cooper pair transistor and ...

Electron temperature probe

2013
The electron temperature probe (ETP) was invented in Japan in 1970’s. The probe measures the electron temperature accurately and the measurement is not influenced by the electrode contamination. The instrument has low weight, low data transmission bit rate and low power consumption.

Low-temperature scanning electron microscopy

Proceedings, annual meeting, Electron Microscopy Society of America, 1983
More than thirteen years have passed since the first micrographs were taken of specimens maintained in a frozen state on the cold stage of a scanning electron microscope (SEM).O) The pictures which were taken showed little we did not already know about the particular cells and tissues but it did demonstrate that this was potentially a powerful ...

Low Temperature Electronics workshop

Sixteenth Annual IEEE Semiconductor Thermal Measurement and Management Symposium (Cat. No.00CH37068), 2002
Interest in cool and cold electronics has increased markedly over the last five years. The benefits of low temperature operation have long been known, but until recently, efforts to commercialize moderate to high volume applications, such as high performance computing, employing high capacity chilling systems have universally failed.

Electron temperature in polar semiconductors

physica status solidi (b), 1968
AbstractUsing the electron temperature approximation an analysis is made of the scattering integral in an intense electric field for a semiconductor with an arbitrary non‐parabolic energy band. The electron temperature is then derived for a purely polar semiconductor with a non‐parabolic dispersion law such as n‐type InSb. The calculations only include

Low temperature semiconductor electronics

InterSociety Conference on Thermal Phenomena in the Fabrication and Operation of Electronic Components. I-THERM '88, 2003
The authors consider that, at any technology level, operation at liquid nitrogen temperature (LNT: 77.3 K) can directly yield a performance improvement exceeding that provided through down-scaling by a factor of two. Thus, MOS technology limits are extended by one generation through LNT operation.

Change of Electron Temperature in an Electron Beam

Journal of Applied Physics, 1953
The effect of electron encounters on the velocity distribution in an electron beam after passage through an accelerating grid is calculated by direct integration of the Boltzmann equation. It is found, with electron densities and velocities typical of traveling wave tubes and diodes, that the electron encounters have a negligible effect, that the ...

Room-temperature electron ratchets

Science, 2020
Device Technology Conventional diodes rectify current flow by forming a junction between dissimilar conductors; a metal-semiconductor diode that forms a Schottky barrier is one example. In these devices, capacitance limits operating frequency. Custer et al.
