The semiconductor band structure describes the range of energy levels that electrons may occupy within a material, crucially defining its electrical properties. Understanding the band structure allows for the manipulation of electron flow, enabling the design of devices like transistors and diodes essential for modern electronics.

Energy levels are discrete values of energy that electrons in an atom can have, determined by quantum mechanics. These levels explain phenomena such as atomic spectra, chemical bonding, and the stability of atoms.

energy levels

Electrical properties refer to the characteristics of materials and systems that determine their behavior in response to electric fields and currents. These properties are crucial for understanding how electrical circuits function and for designing devices that efficiently transmit, store, or convert electrical energy.

Diodes are semiconductor devices that allow current to flow in one direction only, functioning as a one-way valve for electric current. They are essential components in converting alternating current (AC) to direct current (DC) and are used in various applications such as rectifiers, voltage regulators, and signal demodulators.
