摘要

A top-gated MoS₂ transistor with 6 nm thick HfO₂ is fabricated using an ozone pretreatment. The influence to the top-gated mobility brought about by the deposition of HfO₂ is studied statistically, for the first time. The top-gated mobility is suppressed by the deposition of HfO₂, and multilayered samples are less susceptible than monolayer ones.
