Query: Thermal Gating of Charge Currents with Coulomb Coupled Quantum Dots   We have observed thermal gating, i.e. electrostatic gating induced by hot
electrons. The effect occurs in a device consisting of two capacitively coupled
quantum dots. The double dot system is coupled to a hot electron reservoir on
one side (QD1), whilst the conductance of the second dot (QD2) is monitored.
When a bias across QD2 is applied we observe a current which is strongly
dependent on the temperature of the heat reservoir. This current can be either
enhanced or suppressed, depending on the relative energetic alignment of the QD
levels. Thus, the system can be used to control a charge current by hot
electrons.
