Popis: A high Hall-effect mobility of 1,250 cm2V1s−1 is achieved in ZrS2 film as a two-dimensional semiconductor. A large-area atomic-layered polycrystalline ZrS2 film was obtained by sputtering and sulfurization. It was confirmed that a layered ZrS2 film on a SiO2/Si substrate was successfully achieved by a high-temperature sputtering and sulfur compensation process. We demonstrated that the Hall-effect mobility and the carrier density were greatly improved to 1,250 cm2V−1s−1 and $8.5 \times 10^{17}$ cm−3, simultaneously. High-mobility two-dimensional ZrS2 film is a strong candidate for advanced MISFETs.
