The electrical transport properties of the molecular nanosilver chain have been investigated. We observed the symmetric negative differential resistance (NDR) in the current-voltage characteristics. The peak voltage (VP) increased but the peak current (IP) decreased upon cooling. The self-capacitance effect of the silver chain crystal is suggested to explain this unconventional NDR phenomenon.

We present detailed results of the self-consistent analysis of carbon nanotube (CNT) field-effect transistors (FET), previously extended by us to the case of multi-walled/multi-band coherent carrier transport. The contribution to charge transport, due to different walls and sub-bands of a multi-walled CNT, is shown to be generally non-negligible. In order to prove the effectiveness of our simulation tool, we provide interesting examples about current–voltage characteristics of four-walled semi-conducting nanotubes, including details of numerical convergence and contribution of sub-bands to the calculation.

Contact Metal

We report on the calculations of current-voltage characteristics and dynamical resistivity for a model system (series connected point contact metal — superconductor and Josephson junction of the S-N-S type) as a function of applied voltage. Calculated shape of dV/dI as a function of V shows some qualitative agreement with measured curves on real low-resistivity point contacts of the type metal tip – ceramic superconductor (LaBaCuO, YBaCuO). Method for determination of the energy gap is proposed.
