= Dopant activation
{wiki=Dopant_activation}
Dopant activation refers to the process of making a dopant atom incorporated into a semiconductor material electrically active. Dopants are impurities added to a semiconductor (like silicon or gallium arsenide) to modify its electrical properties; they can donate free charge carriers (electrons or holes) that enhance the material's conductivity. When dopants are introduced into a semiconductor, they typically occupy specific lattice sites.
