| Description | The problem addressed is force on an impurity due to electric current. In order to determine the size and direction of the force, as well as its dependence on the voltage, LCAO (Linear Combination of Atomic Orbitals) and the Green's Function approach were implemented. The resultant induced mean force was directed outwards in addition to a smaller component in the electron flow direction. At low bias, force is larger for larger radius, and crosses over the opposite trend when increasing the bias. The crossover current is approximately inversely proportional to the radius. |
