Table 1 Energy spectra of different QDs

From: The effects of porosity on optical properties of semiconductor chalcogenide films obtained by the chemical bath deposition

Shape of a QD

Cube, side a

Prism (square base, side a ), height c > > a

Sphere, diameter a

Prism, triangular base (side a ), height c > > a

Energy spectrum

E = 3 8 h 2 n 2 m a 2

E = 1 4 h 2 n 2 m a 2

E = 1 8 h 2 2 n + 1 2 m a 2

E = h 2 n 2 2 m a 2

  1. Here, n is a quantum number, and m is the effective mass of the particle.
