A quantum well is a potential energy structure where charge carriers (such as electrons and holes) are confined in a very thin region, typically on the nanometer scale. This confinement occurs in one dimension, allowing the carriers to move freely in the other two dimensions. Quantum wells are a key component in various semiconductor devices and have a significant impact on their electronic and optical properties.
