英文摘要 | Two-dimensional(2D)materials have triggered enormous interest thanks to their interesting properties and potential applications,ranging from nanoelectronics to energy catalysis and biomedicals.In addition to other widely investigated 2D materials,GaTe,a layered material with a direct band gap of~1.7 e V,is of importance for applications such as optoelectronics.However,detailed information on the transport properties of GaTe is yet to be explored,especially at low temperatures.Here,we report on electrical transport measurements on few-layered GaTe field effect transistors(FETs)encapsulated by h-BN at different temperatures.We find that by tuning the carrier density,ambipolar transport was realized in GaTe devices,and an electrical-field-induced metal to insulator transition(MIT)was observed when it was hole doped.The mobilities of GaTe devices show a clear dependence on temperature and increase with the decrease of temperature,reaching~1200 cm2 V-1s-1 at 3 K.Our findings may inspire further electronic studies in devices based on GaTe. |
