Abstract
The dependence of the photoionization cross section of hydrogenic impurities on the photon energy was discussed using variational wave function for impurities in cylindrical quantum wires. It was found that the calculation was performed using the infinite confining potential well model. It was observed that the photoionization cross section depended upon locations of the impurity in the wire. Analysis shows that for the polarization of the radiation parallel to the axis of the wire, the cross section initially increased from zero at the threshold frequency for photoionization to occur.
