Overview

Randomized trial investigates electron dynamics in an asymmetric Gaussian potential quantum well, suggesting implications for low-dimensional materials.

Key Points

  • This research aims to explore electron quantum states in strong coupling conditions within an asymmetric Gaussian potential quantum well.
  • Utilized the Pekar-type variational approach for analysis.
  • Determined the eigenenergies and wave functions of ground and excited states.
  • Investigated the oscillation behavior of the electron probability density under varying parameters.
  • Electron probability density displays periodic oscillations with a distinct double-peak structure.
  • Oscillation period varies with electric field strength, decreasing with potential well height and polaron radius.
  • Critical non-monotonic dependence of oscillation period on confinement potential range observed.
