Monolayer WTe2 has been predicted to have zero resistance along its 1D edge as backscattering is protected by time reversal symmetry. However, experiments reveal significant resistance at length scales of 100nm. This project aims to fabricate WTe2 devices and characterise the various scattering mechanisms along the quantum spin hall edge state.
