True or False: Most semiconductors today are made from metal oxides.

The statement that most semiconductors today are made from metal oxides is considered false. While metal oxides do play important roles in certain types of semiconductor applications, such as in thin film transistors and certain types of sensors, the majority of traditional semiconductors, especially those used in the manufacturing of integrated circuits and computer chips, are primarily composed of silicon. Silicon is the most widely used semiconductor material due to its excellent electrical properties and the well-established manufacturing processes that have been developed around it.

In contemporary electronics, there are also developments in new materials such as gallium nitride (GaN) and silicon carbide (SiC), which are used for high-performance applications. Nonetheless, silicon remains dominant. Metal oxides are more specialized rather than the dominant material for semiconductors in general use.

Thus, the correct answer is not "True" because while metal oxides have specific applications, they do not constitute the majority of semiconductor material used today.
