yhdistepuolijohteet
Yhdistepuolijohteet, often referred to as compound semiconductors in English, are materials formed by combining two or more elements, typically from different groups of the periodic table. Unlike elemental semiconductors such as silicon (Si) or germanium (Ge), which consist of a single element, compound semiconductors offer a wider range of electronic and optical properties. This versatility stems from the ability to tailor their bandgap, carrier mobility, and other characteristics by choosing specific combinations of elements and controlling their stoichiometry.
Common examples of yhdistepuolijohteet include gallium arsenide (GaAs), indium phosphide (InP), and gallium nitride (GaN). These
Applications for yhdistepuolijohteet are widespread. Gallium arsenide, for instance, is extensively used in high-frequency integrated circuits
