Fluctuation-Dissipation Limits in Quantum Thermoelectric Transport
Ousi Pan, Zhiqiang Fan, Shunjie Zhang +3
As a fundamental measure of stability in nonequilibrium thermodynamics, fluctuations provide critical insight into the performance and reliability of heat engines. In this work, we…
Geometric Bound for Trade-off Relation in Quantum Tricycle
Shihao Xia, Jingyi Chen, Jincan Chen +1
We establish a finite-time quantum tricycle driven by an external field and investigate its thermodynamic performance in the slow-driving regime. By developing a perturbative expan…
Performance optimization of Nernst-based thermionic engines
Wei Yan, Minglong Lv, Ousi Pan +3
In this paper, we examine the power and efficiency of the thermionic device utilizing the Nernst effect, with a specific focus on its potential application as an engine. The device…
Optimal neutralization of negative space charges in photon-enhanced thermionic emission devices under bidirectional discharge
Xinqiao Lin, Zhiqiang Fan, Shunjie Zhang +4
In this study, we innovatively modeled photon-enhanced thermionic emission (PETE) devices, incorporating positive ion injection and bidirectional discharge's effects on the space c…
Centenary progress from the Nernst theorem to the Nernst statement
Xiaohang Chen, Shanhe Su, Yinghui Zhou +1
It is found from textbooks that there are the different versions of the schematic diagram related to the Nernst equation, and consequently, it leads to some discussion related to t…
Hot-carrier photocatalysts with energy-selective contacts based on quantum wells and dots
Shuanglong Han, Zhiqiang Fan, Ousi Pan +5
In this paper, we simulate the function of hot-carrier photocatalysts (HCPCs) with quantum well and quantum dot energy-selective contacts (ESCs) in the water-splitting reaction. Th…
