Diffusion controlled initial recombination
T. Christen, M. Buttiker
This work addresses nucleation rates in systems with strong initial recombination. Initial (or `geminate') recombination is a process where a dissociated structure (anion, vortex,…
Gauge invariant nonlinear electric transport in mesoscopic conductors
T. Christen, M. Buttiker
We use the scattering approach to investigate the nonlinear current-voltage characteristic of mesoscopic conductors. We discuss the leading nonlinearity by taking into account the…
Partial Densities of States, Scattering Matrices, and Green's Functions
V. Gasparian, T. Christen, M. Buttiker
The response of an arbitrary scattering problem to quasi-static perturbations in the scattering potential is naturally expressed in terms of a set of local partial densities of sta…
Low frequency admittance of a quantum point contact
T. Christen, M. Buttiker
We present a current and charge conserving theory for the low frequency admittance of a quantum point contact. We derive expressions for the electrochemical capacitance and the dis…
Low-frequency admittance of quantized Hall conductors
T. Christen, M. Buttiker
We present a current and charge conserving theory for the low frequency admittance of a two-dimensional electron gas connected to ideal metallic contacts and subject to a quantizin…
