摘要：

Due to very weak screening in nanowires, their conductivity is very sensitive to contact geometry and any wire inhomogeneities. For different geometry of Ohmic contacts, the current-voltage characteristics and frequency dispersion of wire conductivity are calculated for uniform wires and wires with different kinds of inhomogeneities. The effects of Coulomb blockade in nanowires are also discussed. (C) 2000 Elsevier Science B.V. All rights reserved.
