摘要: Electro-static carrier doping was attempted in a layered transition metal disulphide MoS2 by constructing an electric double-layer transistor with ionic liquid. With the application of gate voltage VG higher than 3 V, metallic behavior observed channel. We found onset field-induced superconductivity field induced phase. A maximum TC ∼ 9.4 K observed, which could be those chemically doped bulk materials.
