This volume investigates the theory of the effect of static electric fields on one-electron states in nanocylindrical and nanospherical heterolayers and quantized semiconductor films.

Homogeneous external electrostatic field for all these structures has been considered as a "universal" modulating factor. For structures with radial symmetry, a study on the influence of radial static field and the electric field of a charged ring on one-electron states is presented. Chapters focusing on homogeneous field effect on low-dimensional excitonic states in the quantized films and quantum wires - in both wide bandgap and narrowband semiconductors - are also included. Other contents include calculations on weak, moderate and strong electric fields, quantum-mechanical approximation and perturbation theory, the quasi-classical approximation (WKB method). Readers will benefit from the varied methodological approach to the subject which will give a concrete analytical framework to solve problems related to nanoscale semiconductor design. The reference should prove to be useful to academics and professionals working in semiconductor nanoelectronics research and development.


The book presents the results of theoretical studies of the effects of uniform and radial electrostatic fields on the single-particle states of charge carriers in low-dimensional semiconductor structures: quantum films and cylindrical and spherical quantized layers. The investigations are conducted within the framework of the effective mass approximation. Depending on the geometrical parameters of the sample and the intensity of the external field, various quantum mechanical approximate approaches are used in the computations: the adiabatic approximation, perturbation theory, variation method, and semiclassical approximation. For all the problems considered, the final solutions are obtained in an explicit analytic form. The book is intended for specialists in the field of low-dimensional semiconductor physics.
