I am preparing a draft paper for college and are growing a little, I read an article which says that such as the semiconductors silicon and germanium, have negative temperature coefficients. This means that the electrical resistance of a semiconductor decreases with increasing temperature and increases with decreasing of this"
The processors are made of silicon doped (right?) For which lower the temperature should increase the strength of the material change anything?
Instead, reading the documents for the network (including the IBM prototype 500ghz a helium-cooled liquid), it would seem that you take advantage on the resistance by low temperatures, going completely against the affirmation of my textbook. Some indeed argue that the silicon becomes superconducting at temperatures close to 0 ° K, as to guarantee an ideal overlclock high frequencies and low voltages, as with risk of short circuit.
Well, that's all!
If someone can give me an explanation, thanks!
