Sammanfattning

We present a method for determining a temperature differential across a quantum dot. If the device has a transmission function with sufficiently spaced resonant energies, then one can distinguish electrons which have tunneled from the hot lead, and those which have tunneled from the cold lead. By measuring the thermocurrent as the electrochemical potential is swept through a resonant energy level, information about the transmission function obtained from conductance measurements can be used to deduce the temperature differential of the electron gas across the device.
