| 摘 要： | <正>The transport properties of hexagonal boron-nitride nanoribbons under the uniaxial strain are investigated by the Green's function method.We find that the transport properties of armchair boron-nitride nanoribbon strongly depend on the strain.In particular,the features of the conductance steps such as position and width are significantly changed by strain.As a strong tensile strain is exerted on the nanoribbon,the highest conductance step disappears and subsequently a dip emerges instead.The energy band structure and the local current density of armchair boron-nitride nanoribbon under strain are calculated and analysed in detail to explain these characteristics.In addition,the effect of strain on the conductance of zigzag boron-nitride nanoribbon is weaker than that of armchair boron nitride nanoribbon.
