Question
Download Solution PDFTemperature coefficient of resistance in a pure semiconductor is __________.
Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFEffect of temperature on resistance of different material:
Conductor: When the temperature of conducting material increases, the resistance of that particular material increases.
Insulator: When the temperature of conducting material increases, the resistance of that particular material decreases.
Semiconductor: When the temperature of semiconducting material increases, the resistance of that particular material decreases.
A negative coefficient for a material means that its resistance decreases with an increase in temperature. Hence, pure semiconductor materials (silicon and germanium) typically have negative temperature coefficients of resistance.
