Laser-Beam-Patterned Topological Insulating States on Thin Semiconducting MoS2
Abstract
Identifying the two-dimensional (2D) topological insulating (TI) state in new materials and its control are crucial to the development of voltage-controlled spintronic devices with low power dissipation. However, their experimental observation is rare. Members of the 2D material family of transition metal dichalcogenides (TMDCs) have been recently predicted and experimentally reported as a new class of 2D TI materials. Here, we realize controlled patterning of the 1T'-phase onto thin 2H-semiconducting molybdenum-disulfide (MoS2) only by laser beam irradiation. Integer fractions of the quantum value of resistance are observed for two-different 1T' patterns, indicating the presence of helical edge spin modes, characteristic of 2D TI state, at the 1T'/2H phase interface. This result is supported by resistance dependence on laser-irradiation time and power, magnetic field, and temperature, scanning tunneling spectroscopy, and theoretical calculations. The present observation opens the door to the controlled patterning of topological phases into non-topolog ical phases of TMDCs and their application to topological quantum computation.
