To calculate and evaluate the quantum size effects occurring during the electric field effect in ultra-thin bismuth films.
Modeled field penetration across films using a self-consistent Thomas-Fermi-type approximation.
Calculated local conductivity using the relaxation time approximation, setting the relaxation time to vary inversely with the electronic density of states.
Evaluated conductance profiles across different film thicknesses and thermal conditions.
Film conductance exhibited abrupt, discontinuous changes with an applied electric field when thickness positioned the Fermi level near a step in the electronic density of states.
Demonstrated that the manifestation and sharpness of the quantum size effect are directly modulated by temperature.
