Plasmonic Thermal Conductance of Stack of Metallic Nanorings
In this paper, we study the plasmonic thermal conductance of ordered stacks of metallic nanorings in a host material. Using second quantized formalism of the Random Phase Approximation, we first determine the dispersion relations of surface plasmon waves on the stacks of nanorings. Then, using Landauer-Buttiker formalism, we determine the coefficient of plasmonic thermal conductance and heat cu...
متن کاملSensitivity Analysis of Different Parameters Affecting Thermal Contact Conductance
In internal combustion engines, exhaust valve and its seat gain considerable temperature as the hot gases exit through them. So, the rate of heat transfer should be under control. In this study, the contact heat transfer coefficient has been estimated. An experimental study on an Air-Cooled internal combustion engine cylinder head has been considered. Using the measured temperatures of sensors ...
متن کاملMeasurement of single-molecule conductance.
What is the conductance of a single molecule? This basic and seemingly simple question has been a difficult one to answer for both experimentalists and theorists. To determine the conductance of a molecule, one must wire the molecule reliably to at least two electrodes. The conductance of the molecule thus depends not only on the intrinsic properties of the molecule, but also on the electrode m...
متن کاملThermal Conductance of a Single-Electron Transistor.
We report on combined measurements of heat and charge transport through a single-electron transistor. The device acts as a heat switch actuated by the voltage applied on the gate. The Wiedemann-Franz law for the ratio of heat and charge conductances is found to be systematically violated away from the charge degeneracy points. The observed deviation agrees well with the theoretical expectation....
متن کاملQuantised Thermal Conductance
In 1983 J Pendry published a paper on the quantum limits to the flow of information and entropy [Pendry'83]. In it he showed that there is an inequality that limits the flow of information as a function of the energy flow. He applied this relationship to calculate the limit on the rate of heat flow in a channel and found that this had to be 1 2 2 3 1 − ≤ h T kB π where kB is Boltzmann constant ...
