A quantum well is a potential well with only discrete energy values. The classic model used to demonstrate a quantum well is to confine particles, which were originally free to move in three dimensions, to two dimensions, by forcing them to occupy a planar region.

Semiconductor Physics: Density of States To calculate various optical properties such as the rate of absorption or emission and how electrons and holes distribute themselves within a solid, we need to know the number of available states per unit volume per unit energy.

Meanwhile, colloidal nanocrystals have gained a high level of maturity from a material perspective and now achieve a broad.

Finite Barrier Quantum-Well In the last section, we looked at the p-n junction. More efficient recombination of electron-hole pairs can be acheived by incorporation of a thin layer of semiconductor material, either p or n type semiconductor with a smaller energy gap than the cladding layers, to form a double heterostructure.
