Quantum Pits Quantum pits are fascinating semiconductor heterostructures that confine electrons and holes in two dimensions, creating unique electronic and optical properties. These structures are typically formed by growing a thin layer of a narrow-bandgap semiconductor, such as indium gallium arsenide (InGaAs), between two layers of a wider-bandgap semiconductor, such as gallium arsenide (GaAs). In … Read more
