Which of the following is a n-type intrinsic semiconductor?
-
Bromine pentafluoride
-
Bromine trifluoride
-
Cacodylic acid
-
Cadmium arsenide
D
Correct answer
Explanation
Cadmium arsenide is a crystalline semiconductor with a tetragonal structure in the II-V family. It is a n-type intrinsic semiconductor. Cadmium arsenide is used in infrared detectors using Nernst effect, and in thin-film dynamic pressure sensors. It can also be used to make magnetoresistors, and finds use in in photodetectors.
