A quantum well is a thin layer of semiconductor material that confines the movement of charge carriers to two dimensions. Derive an expression for the density of quantum states dN/dE. Consider the problem in the following parts: X Z Quantum Well Figure 2: Example of a quantum well device (a) Extrapolate the 1D infinite well solution to 2D infinite well (b) You may assume the Fermi geometry is a circle (c) Find the N states and then take the derivative of that expression to find the density of quantum energy states.
