Balancing Power, Efficiency, and Constancy under Broken Time-Reversal Symmetry
Ousi Pan, Zhiqiang Fan, Shunjie Zhang +3
We derive general trade-off relations among the power, efficiency, and constancy for two-terminal thermoelectric systems in the linear response regime. Constancy, which quantifies…

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…
