Which of the following oxides is commonly used as a semiconductor material in electronic devices and solar panels?
Silicon dioxide
Aluminum oxide
Titanium dioxide
Iron oxide
Silicon dioxide is commonly used as a semiconductor material in electronic devices and solar panels. It has a crystalline structure and can conduct electricity when doped with small amounts of impurities. It is also used as an insulator to protect electronic components from moisture and other contaminants.
Explanation of incorrect option
incorrect option B Aluminum oxide, also known as alumina, is used in a variety of applications such as in the production of ceramics, glass, and as a catalyst. However, it is not commonly used as a semiconductor material.
incorrect option C Titanium dioxide is a white pigment that is used in paint, sunscreen, and other products. It is not commonly used as a semiconductor material.
incorrect option D Iron oxide, also known as rust, is a common compound of iron and oxygen. It is not used as a semiconductor material, but rather as a pigment in paints and coatings.
