Interface modulated electron mobility enhancement in core-shell nanowires
文献摘要:
The transport properties of core-shell nanowires(CSNWs)under interface modulation and confinement are investi-gated based on the atomic-bond-relaxation(ABR)correlation mechanism and Fermi's golden rule.An analytical expression for the relationship between carrier mobility and interface mismatch strain is derived and the influence of size,shell thick-ness and alloyed layer on effective mass,band structures,and deformation potential constant are studied.It is found that interface modulation can not only reduce the lattice mismatch to optimize the band alignment,but also participate in the carrier transport for enhancing mobility.Moreover,the underlying mechanism regarding the interface shape dependence of transport properties in CSNWs is clarified.The great enhancement of electron mobility suggests that the interface modulation may become a potential pathway to improving the performance of nanoelectronic devices.
