Conduction in molecular junctions: Inelastic effects
Dvira Segal, Abraham Nitzan
The effect of a thermal environment on electron (or hole) transfer through molecular bridges and on the electron conduction properties of such bridges is studied. Our steady state…
Traversal times for resonant tunneling
Uri Peskin, Michael Galperin, Abraham Nitzan
The tunneling time of particle through given barrier is commonly defined in terms of "internal clocks" which effectively measure the interaction time with internal degrees of freed…
Numerical simulations of electron tunneling currents in water
Michael Galperin, Abraham Nitzan, Ilan Benjamin
This paper presents results of numerical simulations of electron tunneling through water that extend our previous calculations on such systems in several ways. First, a tip-substra…
Heating in current carrying molecular junctions
Dvira Segal, Abraham Nitzan
A framework for estimating heating and expected temperature rise in current carrying molecular junctions is described. Our approach is based on applying the Redfield approximation…
Inelastic effects in electron tunneling through water layers
Michael Galperin, Abraham Nitzan
Calculations of tunneling matrix elements associated with electron transfer through molecular environments are usually done for given frozen nuclear configurations, assuming that n…
Traversal time for electron tunneling in water
Michael Galperin, Abraham Nitzan, Uri Peskin
The traversal time for tunneling is a measure of the time during which the transmitted particle can be affected by interactions localized in the barrier. The Buttiker-Landauer appr…
