Quantum wells are thin layers of a material in which electrons are confined to two dimensions, creating a potential well in the third dimension. These structures are commonly used in semiconductor devices to control the movement and behavior of electrons, leading to unique quantum effects and enhanced device performance. Quantum wells have been extensively studied for their applications in optoelectronics, such as lasers and photodetectors, as well as in quantum computing and information processing. Research in this area focuses on understanding and optimizing the properties of quantum wells to improve the efficiency and functionality of various electronic and photonic devices.
