Semiconductor materials are the basis of modern electronics Conduction band (e.g. the transistors, memory and camera in your cell phones). Common semiconductor materials include Si, GaAs and CdSe. The energy states of semiconductors are generally divided into the valence band, where the electrons are bound to the atoms, 2S(e) 1D(e) and the conduction band where the wavefunction solutions of 1P(e) electrons allow some of them (the excited electrons) to move through the bulk material. The energy difference between the maximum energy level of the valence band, termed the valence band maximum (VBM), and the lowest energy of the conduction band, termed the conduction band minimum (CBM), of bulk CdSe is 1.74 eV. As shown in the figure, this difference is known as the bandgap energy, Eg. The CBM can be regarded as the excited state while the VBM can be regarded as the ground state. (we will not concern ourselves with the S, P, etc. orbital designations in the figure). 1S(e) Eg(QD) | 1S(h)…
