Density of states for 3d

WebStudents will remember that the partition function for a gas is calculated using the density of states, which is itself dependent on the dispersion relation. In an ideal gas, the dispersion relation is quadratic (see box below) while for a gas of ultra-relativistic particles, the dispersion relation is linear. Therefore, we find: WebThe resulting density of states for a quantum well is a staircase, as below in red. Further restriction of the semiconductor dimensionality to 1-D (quantum wire) and 0-D (quantum …
