Photoelectric emission from quantum wells with various potential profiles
The subband energies in a quantum well (QW) with rectangular, triangular and parabolic potential profiles are calculated. The subband energies for rectangular QW are found to be the lowest among the three cases, while those for the triangular well are higher than the parabolic potential profile case. The photoelectric (PE) current density as a function of the well width and the incident photon energy is investigated for all the cases. The effect of size quantization is quite evident in all cases from the oscillatory variation of the PE current density.
