Transition metal ditellurides (TMDT) exhibit various physical phenomena originating from the strong spin-orbit coupling. In particular, it is known that Td phase bilayer WTe2 exhibits the non-linear Hall effect (NLH), which can occur in a time-reversal symmetric condition. However, due to a small difference in the electronegativities of tungsten/molybdenum and tellurium, it is difficult to synthesize uniform and clean few-layer WTe2 or MoTe2 single crystals via a common chemical vapor deposition (CVD) method.
