Reversible conductivity transformations in chalcogenide alloy films
Journal of Non-Crystalline Solids, 1970Certain amorphous chalcogenide alloys, such as Ge15Te85, exhibit metastable conductivity. These reversible structural changes in amorphous alloys entailing variation in order and conductivity have been made the basis of memory devices.(1) In this paper, we present our observations on induced conductivity transformation from one state to another ...

Power MOSFETs reverse conduction revisited
PESC '91 Record 22nd Annual IEEE Power Electronics Specialists Conference, 2002A contribution to the characterization of power MOS transistors under optimized switching behavior is presented. Reverse conduction through the channel resistance is imposed, avoiding the problem of integral diode recovery time without using external diodes. The control circuit design is discussed.

Conducting properties of mixed reverse micelles
Colloids and Surfaces A: Physicochemical and Engineering Aspects, 1999Abstract The conducting properties of mixed reverse micelles formed with AOT and other surfactants have been investigated, with the emphasis on the effect of solvents and surfactant composition. The phenomena observed were interpreted according to the formerly proposed physical meaning of W0,max, which stands for the molar ratio of water to ...

The application of semiconductor devices in power installations is continuously growing due to the improved performance and the resulting cost reductions of such systems. This advancement is made possible by adapting the device characteristics to the circuit requirements. This is particularly the case with reverse-conducting thyristors.

Development of SiC Merged Reverse Conductive Devices
IEEJ Transactions on Industry Applications, 2020AbstractSiC merged reverse conductive (MRC) power devices composed of both unipolar devices and bipolar devices have been developed to achieve a smaller chip size, a lower power loss, and a higher reliability. SiC MRC power devices such as SiC MRC‐MOSFET and SiC MRC‐IGBT can achieve this performance, but have the problems of on‐voltage degradation and ...

A new cuff electrode for reversible conduction blocking
Journal of Neuroscience Methods, 1991A cuff electrode of novel design (rigid body and lid) is presented. It contains a closed cavity surrounding the nerve, through which a cooled liquid (Ringer solution) can be circulated. Recording sites at both ends of the cavity permit monitoring of the conduction blocking, which occurs at different temperatures for different units. Reversible blocking

Time Reversal in Heat Conduction
American Journal of Physics, 1965The mathematical consequences of assuming heat conduction (or diffusion of particles) in the same sense as the temperature (or concentration) gradient rather than in the opposite sense leads to time reversal in the partial differential equation and the possibility of computing a prior state of temperature from one known in the present.

Progressive and Reversible Conduction Disease With Checkpoint Inhibitors
Canadian Journal of Cardiology, 2017Novel antineoplastic therapies are focused on harnessing our own immune system to fight cancer. To that end, cytotoxic T-lymphocyte-associated antigen 4 and programmed death ligand 1 are 2 coinhibitory signals that play central roles in decreasing T-cell response and represent a class of medications termed "checkpoint inhibitors." We present an unusual
