A Si sample is doped with a fixed number of group N impurities. The electron density n is measured from 4 K to 1200 k for the sample. Which one of the following is correct?-A-n remains constant over the temperature rangeB-n increases monotonicaliy with increasing tempC-n increases first remains constant over a range and again increases with increasing temperatureD-n increases show a peak and then decrease with temperature-B-n increases monotonicaliy with increasing temp

Question

APTITUDE CRACK · Accepted Answer

B n increases monotonicaliy with increasing temp The doping concentration is directly proportional to T^3/2 and also to the e^1/t.
