Exciton energy in quantum wires
This tutorial aims to calculate the exciton binding energy for 2D quantum
wires (QWRs).
In order to correlate the calculated optical transition energies of a 2D
quantum wire (QWR) to experimental data, one has to include the exciton
(electronhole pair) corrections. In this tutorial we study the exciton
correction of the electron ground state to the heavy hole ground state (e1 
hh1).
In
Paul Harrison's
book "Quantum
Wells, Wires and Dots" (Section 6.5 "The twodimensional and
threedimensional limits"), the exciton energy has been calculated for CdTe
quantum wells, see 1D tutorial "Exciton energy in quantum wells".
Here, we calculate the exciton energy in quantum wires where we also try to approach
the limits of "bulk" and "quantum well".
