“…According to the Langevin formula DMS or Larmor DMS (in a.u.) is given by [44], [48]χdia=−e26m⁎εc2〈(r−r0)2〉, where r0 is the dopant coordinate. false〈true(r−r0true)2false〉 stands for the variance of the separation between the impurity and the dot confinement center.…”

In the present work we explore the role of noise-binding energy (BE) interplay on the diamagnetic susceptibility (DMS) of doped GaAs quantum dot (QD). Gaussian white noise has been invoked for the above exploration. And Gaussian impurity acts as a dopant in the present study. The mode of inclusion of noise to the system significantly affects the above interplay and thus prominently modulates the DMS profile. The outcomes of the inspection unfolds the way by which DMS of doped QD can be regulated by prudent adjustment of noise-BE interaction.

Linear and nonlinear susceptibilities in GaN/Al _x Ga_1−xN quantum wire

In this work, we have performed a new approach based on a combination of coordinate transformation and the finite difference method in order to investigate the electronic, linear and nonlinear optical properties of GaN/AlxGa1−xN quantum wire. The real and the imaginary parts of first-order linear and third-order nonlinear susceptibilities are investigated as a function of the quantum wire height and Aluminum mole fraction. Our calculations revealed that as the height increases, the transition energy decreases monotonically. In addition, the peaks of susceptibility decreased and shifted to the red as the height augments. Our findings can serve the experimental studies linked to practical exploitation of the quantum confinement effect in optoelectronic devices based on quantum wire nanostructures.
