Flashcards

Semiconductor Materials

Silicon, germanium, and gallium arsenide are the primary materials used in semiconductor devices.

Conductivity of Semiconductors

Semiconductor devices have conductivity levels that fall between conductors and insulators.

Vacuum Tubes Replaced

Semiconductor devices have replaced vacuum tubes in numerous applications due to their smaller size, lower power consumption, and greater reliability.

Solid-State Conduction

Semiconductor devices conduct electric current through the movement of electrons within their solid-state structure, unlike vacuum tubes which relied on electron flow in a vacuum.
