An n-type semiconductor is known to have an electron concentrati An n-type semiconductor is known to have an electron concentration of 3 ( 1018 m-3. If the electron drift velocity is 100 m/s in an electric field of 500 V/m, calculate the conductivity of this material.
An FCC iron-carbon alloy initially containing 0.35 wt% C is An FCC iron-carbon alloy initially containing 0.35 wt% C is exposed to an oxygen-rich and virtually carbon-free atmosphere at 1400 K (1127(C). Under these circumstances the carbon diffuses from the alloy and reacts at the surface with the oxygen in the atmosphere; that is, the […]
