Effects of Polaron and Quantum Confinement on the Nonlinear Optical Properties in a GaAs/Ga_1−𝑥Al_𝑥As Quantum Well Wire

Figure 1

Binding energy of an impurity as a function of wire radius in a GaAs/Ga_0.8Al_0.2As quantum well wire with and without the polaron effects. Curve (1) represents for the LO phonon contribution and curve (2) contributes for the phonon corrections. The insert figure shows the corresponding polaronic shift due to LO phonons.
