Originální abstrakt

Behavior of a nanostructure consisting of Si quantum dot (QD) embedded in SiO2 dielectric medium, which is under bias of varying electrostatic field is simulated. The paper presents the wave functions psi, probability functions psi.psi* and energies of quantum states of a QD. Abrupt displacement of the peak of psi.psi* at a certain field value is elucidated as electron emission. The field distribution and the characteristics of the nanostructure quantum states are simulated numerically with help of Comsol Multiphysics Poisson-Schrödinger 2D model, developed by the authors.
