We study the optimal output power and efficiency of the three-terminal quantum heat engine with Coulomb-coupled quantum-dots (CCQD). It has been well known that in the weak coupling regime, two kinds of dominant transport mechanisms are sequential tunneling and cotunneling processes in CCQD. What process becomes dominant, which can be controlled by several parameters such as temperature difference, bias voltage, Coulomb interaction and tunneling parameters, is one of the key problems to… Expand


Three-terminal quantum-dot refrigerators.
Based on two capacitively coupled quantum dots in the Coulomb-blockade regime, a model of three-terminal quantum-dot refrigerators is proposed and the transport properties of steady-state charge current and energy flow between two quantum dots and thermal reservoirs are revealed. Expand

Enhancement of the thermoelectric figure of merit in a quantum dot due to the Coulomb blockade effect
We investigate the figure of merit of a quantum dot (QD) in the Coulomb blockade regime. It is found that the figure of merit $ZT$ may be quite high if only single-energy level in the QD isExpand
Single-electron thermal devices coupled to a mesoscopic gate
We theoretically investigate the propagation of heat currents in a three-terminal quantum dot engine. Electron-electron interactions introduce state-dependent processes which can be resolved byExpand
Thermoelectric energy harvesting with quantum dots.
This work focuses on quantum dots in the Coulomb-blockade regime, chaotic cavities and resonant tunneling through quantum dots and wells, and quantum-dot heat engines that are driven by bosonic degrees of freedom such as phonons, magnons and microwave photons. Expand
Thermoelectric Conversion at 30 K in InAs/InP Nanowire Quantum Dots.
High-temperature thermoelectric conversion in InAs/InP nanowire quantum dots is demonstrated by taking advantage of their strong electronic confinement and investigating the evolution of the electronic figure of merit ZT as a function of the quantum dot configuration. Expand
