SINGLE-ELECTRON TUNNELING AT HIGH-TEMPERATURE

The electromagnetic environment in which a small tunnel junction circu it is embedded plays a crucial role in its transport properties. Altho ugh the theory of single-electron tunneling is well established, few a nalytical results are known. We use a real-time formulation to obtain new predictions for the high-temperature conductance of single-and dou ble-junction systems in series with a resistor. We discuss the implica tions of our results for recently proposed metrological thermometry ba sed on Coulomb blockade of single-electron tunneling.
