Abstract
In the effective-mass approximation the single-electron states in a wide-band semiconductor nanocylindrical heterolayer in the presence of strong lateral-radial electrical field are considered. The explicit forms of the energy spectrum and envelope wave functions of single-particle states for charge carriers are obtained using variation approach. Corresponding absorption characteristics of interband and inter-subband optical transitions in the layer in the presence of strong radial field are calculated. The radial field leads to the explicit dependence of absorption intensity on the values of effective masses of charge carriers. It is shown that absorption's threshold frequencies depend explicitly on geometrical sizes of sample and intensity of external field.
