dc.description.abstract2D hexagonal lattice Topological Insulator(TI) shows topologically protectedspin polarized edge transport while the bulk of the material remains insulating.Thesuppressionofbackscatteringofelectronsmakestheedgetransportofelec-trons robust against any perturbation. Elastic phonon dephasing represents ageneralized scattering and dephasing mechanism. In this work, we have illus-trated the effect of elastic phonon dephasing on the transport of electron in 2Dhexagonal lattice TI using Non Equilibrium Green’s Function (NEGF) formal-ism.Thetransmissionwasfoundtobeunity(1)andthephaseoftheelectronre-mained coherent even after strong phonon dephasing. The results of this paperindicate the suitability of TI in future dissipationless coherent nanoelectronicdevices.
