TL;DR: In this article, the polar optical phonon scattering limited mobility in 1-DEG quantum wire of GaAs and the variation of mobility with well width for 1D GaAs quantum wire has been studied.
Abstract: The polar optical phonon (POP) scattering limited mobility in 1-DEG quantum wire of GaAs has been investigated The variation of mobility with well width for 1D GaAs quantum wire has been studied The mobility dependence on the transverse dimension of quantum wire for different values of electron energy has been also been investigated The results obtained at 300K for GaAs wire reveal that the variation is almost linear in nature

TL;DR: In this article, the effect of geometry on an on-center hydrogenic donor impurity in a GaAs/(Ga,Al)As quantum wire (QWW) and quantum dot (QD) under the influence of Γ-X band mixing due to an applied hydrostatic pressure is theoretically studied.
Abstract: The effect of geometry on an on-center hydrogenic donor impurity in a GaAs/(Ga,Al)As quantum wire (QWW) and quantum dot (QD) under the influence of Γ–X band mixing due to an applied hydrostatic pressure is theoretically studied. Numerical calculations are performed in an effective mass approximation. The ground state impurity energy is obtained by variational procedure. Both the effects of pressure and geometry are to exert an additional confinement on the impurity inside the wire as well as dot. We found that the donor binding energy is modified by the geometrical effects as well as by the confining potential when it is subjected to external pressure. The results are presented and discussed.
