Question

which of the following is a semiconductor ?
1) diamond
2) gallium arsenide
3) phosphorus
4) arsenic​

Answer 1

Answer:

The answer is 4 Arsenic

Answer 2

Gallium Arsenide is a semiconductor. (Option 2)

• Semiconductors are materials with conductivities that fall somewhere between conductors and nonconductors or insulators.
• Pure elements like silicon and germanium, as well as compounds like gallium arsenide and cadmium selenide, are used to make semiconductors.
• Semiconductors are made up of a variety of elements, with gallium arsenide, germanium, and silicon being among the most often utilized.
• Electrical circuits are made of silicon, whereas solar cells, laser diodes, and other devices are made of gallium arsenide.
