Figure 3From: Thermoelectric effect in an Aharonov-Bohm ring with an embedded quantum dotFigure-of-merit ZT as a function of the intradot level ε d and inter-lead coupling strengths t LR for different dot-lead coupling strengths: (a) t d = 0.1; (b) t d = 0.2; (c) t d = 0.3; (d) t d = 0.4. The magnetic flux and the Coulomb interaction are all set to be zero.Back to article page
