Temperature effect on conductivity

An intrinsic semiconductor at absolute zero, behaves as a perfect insulator. The amount of energy required to break a covalent bond is 0.72 eV in case of germanium and 1.11 eV in case of silicon. Equivalently, we

Resistance temperature detector (RTD)

The thermometer in which the resistance of conductor changes with change in temperature is known as resistance thermometer. The resistance thermometer is also called as resistance temperature detector (RTD). Construction: The resistance temperature detector (RTD) consists of
