 abstract = {Investigation of quantum spin Hall states in 1T' phase of the monolayer
transition metal dichalcogenides has recently attracted the attention
for its potential in nanoelectronic applications. While most of the
theoretical findings in this regard deal with infinitely periodic
crystal structures, here we employ density functional theory
calculations and k.p Hamiltonian based continuum model to unveil the
bandgap opening in the edge-state spectrum of finite width molybdenum
disulphide, molybdenum diselenide, tungsten disulphide and tungsten
diselenide. We show that the application of a perpendicular electric
field simultaneously modulates the band gaps of bulk and edge-states. We
further observe that tungsten diselenide undergoes a semi-metallic
intermediate state during the phase transition from topological to
normal insulator. The tuneable edge conductance, as obtained from the
Landauer-Buttiker formalism, exhibits a monotonous increasing trend with
applied electric field for deca-nanometer molybdenum disulphide, whereas
the trend is opposite for other cases.},
