In semiconductors, it is possible to make actual potential wells by sandwiching a d-deDUwelld-deDt layer of one semiconductor material (such as InGaAs) between two d-deDUbarrierd-deDt layers of another semiconductor material (such as InP). In this structure, the electron has lower energy in the d-deDUwelld-deDt material, and sees some potential barrier height Vo at the interface to the d-deDUbarrierd-deDt materials. This kind of structure is used extensively in, for example, the lasers for telecommunications with optical fibers. In semiconductors, such potential wells are called d-deDUquantum wellsd-deDt.(*)This m-file (GaAs_QW) calculates the energy levels in a GaAs single quantum well with constant effective mass vs. different well widths. It also plots the corresponding eigenfunctions given the potential energy and well width.(*) David. A. B. Miller, Quantum Mechanics for Scientist and Engineers. Cambridge.PhD Student.
