Summary on Grant Application Form
Recently there has been growing experimental evidence for, and interest in, current-induced mechanical effects in atomic-scale conductors. There are two such effects - additional forces on atoms and local heating. Recently we have developed a tight-binding formalism to calculate current-induced forces on atoms in a general metallic nanojunction. The purpose of the present project is to model the other current-induced effect, namely local heating. The two combined would provide the first complete description of current-induced mechanical effects in nanoscale conductors.The proposed simulation of the temperature profile in a current-carrying metallic nanojunction uses the same tight-binding methodology as our calculations of current-induced forces. This temperature simulation consists of two parts. First, we will calculate the power delivered to each atom in the junction by the current. Second, we will use a classical dynamical simulation to enable the system to set up a corresponding steady-state temperature profile.In our work on transport in atomic-scale conductors, we have maintained a close interaction with experimentalists from Leiden, Aarhus and Madrid. The proposed simulations of current-induced heating - like our work on current-induced mechanical effects as a whole - will be done in collaboration with them.
