Why in a conductor increase in temperature makes the atoms vibrate but in a semiconductor the kinetic energy of the free electrons is increased?
When temperature is increased in case of a semiconductor the free electron gets more energy to cross the energy gap to the conduction band from the valence band.so now more electrons can go easily to ...

Are thermistors and filament bulbs ohmic?
Conductors are ohmic if they have a constant resistance given that the physical conditions, such as temperature, are constant.
A filament bulb and thermistor are considered to be non-ohmic because ...

Differences in conductivity as temp rises for intrinsic vs extrinsic semiconductrs
For a doped semiconductor, near the end of the extrinsic temp region due to heightened effects of lattice scattering conductivity goes down "temporarily" (temperature wise).
What happens to the ...

How does temperature affect an electrical current
Synopsis
I have read an interesting article J. Halderman et al. "Lest we remember: cold boot attacks on encryption keys" in computer science regarding cold booting.
The paper discusses how the use ...
