Halbleiterverbindungen

Halbleiterverbindungen, also known as compound semiconductors, are materials composed of two or more elements that exhibit semiconducting properties. Unlike elemental semiconductors like silicon, which consist of a single element, compound semiconductors are formed from combinations of elements, often from different groups of the periodic table. Common examples include gallium arsenide (GaAs), indium phosphide (InP), and gallium nitride (GaN).

The unique electronic and optical properties of these materials arise from the specific arrangement of atoms and the resulting band structure. This allows for a wider range of applications than elemental semiconductors. For instance, compound semiconductors are crucial for high-frequency electronics, optoelectronic devices such as light-emitting diodes (LEDs) and lasers, and high-power electronics. Their ability to emit and detect light efficiently makes them indispensable in modern communication technologies, displays, and solar cells. The precise control over their properties through careful selection of constituent elements and growth conditions makes them highly versatile in advanced technological fields.
