Question

Which of the following is the disadvantage of silicon semiconductor detector?

(a) Low stable

(b) Can be operated only at low temperatures

(c) Have low count-rate

(d) Low resolution

This question was addressed to me in a national level competition.

I need to ask this question from X-Ray Fluorescent Spectrometer in chapter X-Ray Spectrometers of Analytical Instrumentation

Answer 1

The correct choice is (b) Can be operated only at low temperatures

To elaborate: The disadvantage of silicon semiconductor detector is that they can be operated only at low temperatures. They have high stability, high count-rate and adequate resolution.
