Abstract: C1.00110 : Asymmetric Double Quantum Dot Energy States in a Quantizing Magnetic Field
Author:
This work is concerned with electron states and propagation in a
two-dimensional asymmetric quantum double-dot system embedded in
a two
dimensional host sheet subject to Landau quantization. The two
dots are
represented by two Dirac delta function potential terms of
differing depths
each of which would support just one subband state if the other
were absent,
if there were no magnetic field. The integral equation for the
Schrodinger
Green's function for this double-dot system is solved exactly in
closed form
in terms of the infinite sheet Green's function for two dimensional
electrons subject to Landau quantization with no quantum dots. The
dispersion relation for the double dot subband energies is
formulated and
examined by analyzing the frequency poles of the Green's function
with
Landau-quantization-like splintering of the levels by the
magnetic field.
The effects of the asymmetry in regard to the potential well
depths are
analyzed as functions of the well-depth difference and
dot-separation.
