-
Hypophosphorous acid
-
Indium antimonide
-
Indium arsenide
D
Correct answer
Explanation
Indium arsenide is a semiconductor material. It has the appearance of grey cubic crystals with a melting point 942 °C. Indium arsenide is used for construction of infrared detectors, for the wavelength range of 1-3.8 µm. The detectors are usually photovoltaic photodiodes.
