Question

5. Why are germanium and silicon referred to as semiconductors?

Answer 1

• Semiconductor: A substance having conductivity between that of a conductor and an insulator
• The metalloids are a group of six elements listed in the periodic table between metals and non-metals. They are boron, silicon, germanium, arsenic, antimony, and tellurium.
• Conduction of heat and electricity silicon, germanium, and tellurium conduct electricity under the right conditions. They are semiconductors. Metalloids conduct less heat than metals.
