Semiconductors are materials whose electrical conductivity lies between that of conductors and insulators, and they are unique because their properties can be controlled and modified.

Semiconductors are chemically diverse materials whose electrical conductivity lies between that of conductors and insulators, and their behavior can be precisely engineered.

The most common elemental semiconductors are silicon (Si), germanium (Ge), and tin (Sn), all from Group IV of the periodic table.

Compound semiconductors expand this range by combining elements from different groups: III–V compounds like gallium arsenide (GaAs), indium phosphide (InP), and gallium nitride (GaN) are used in high-speed and optoelectronic applications, while II–VI compounds such as zinc oxide (ZnO), cadmium telluride (CdTe), and mercury cadmium telluride (HgCdTe) serve in solar cells and infrared detectors.

IV–IV compounds like silicon carbide (SiC) and silicon germanium (SiGe) offer high thermal stability and are used in power electronics and integrated circuits.

Organic semiconductors, including pentacene and P3HT, are carbon-based molecules used in flexible electronics and OLEDs.

Oxide semiconductors like indium tin oxide (ITO) and tin oxide (SnO₂) are transparent and conductive, making them ideal for displays and sensors.

Additionally, amorphous and alloyed semiconductors such as amorphous silicon (a-Si) and ternary/quaternary alloys like AlGaInP allow for fine-tuning of band gaps and lattice properties. Together, these materials form the chemical foundation of modern electronics, each tailored for specific performance, environmental, and optical requirements.

Unlike metals, semiconductors have a band gap that restricts electron movement, but this gap is small enough that conductivity can be influenced by temperature, light, or the addition of impurities, a process known as doping.

When doped with specific elements, semiconductors can be engineered to favor either electrons or holes as charge carriers, creating n-type or p-type materials.

This tunability makes semiconductors the foundation of devices such as transistors, diodes, solar cells, and integrated circuits.

Their ability to switch and amplify signals revolutionized technology, enabling the development of computers, smartphones, and countless other electronic systems. Semiconductors are therefore not just materials but the cornerstone of the digital age, bridging physics and engineering in transformative ways.
