Electrical conductivities of semi-conductors are of the order of ______________ ohm/cm ?
Correct answer: A. 10-3
- A. 10-3
- B. 103
- C. 10-15
- D. 1015
Explanation
Semiconductors have conductivities much lower than metals but much higher than insulators, commonly lying around 10^-3 ohm^-1 cm^-1 for the order used in this question. The other values represent metallic or insulating extremes.
