摘　　要：Benefiting from good electrostatics,excellent combinations with high-j oxide dielectrics,and high device densities,Si fin field-effect transistor(FinFET)arrays are the dominant structures of current complementary metal oxide semiconductor technology.However,when Si FinFETs are extremely small,their performance deteriorates significantly due to enhanced interfacial scattering arising from thickness fluctuations and dangling bonds.In fact,the Si carrier mobility degrades drastically with the thickness:l/t 6(where l is the mobility and t is the thickness of the semiconductor)[1].Two-dimensional(2D)materials,such as graphene,transition metal dichalcogenides(TMDs),black phosphorus,and Bi2O_(2)Se,have emerged as promising building blocks for nextgeneration FETs.They exhibit excellent electrostatics due to their atomic scale thicknesses and high carrier mobilities(up to 103 cm^(2) V1 s1)from their smooth surfaces without dangling bonds[2].
