Counting Statistics of Parallel Al atomic wires
Ying-Tsan Tang, Yu-Chang Chen
We have studied how the lateral interaction affects the electric conductance, the second-order current correlation (shot noise), and the third-order one (skewness) of a pair of par…
Current Streamline Flow on Current-induced Effects in Highly Asymmetric Molecular Junctions
Bailey C. Hsu, Allen Tseng, Yu-Chang Chen
From first-principles approaches, we illustrate that the current-induced forces and the selection rule for inelastic effects are highly relevant to the current density in an asymme…
Seebeck Coefficients in Nanoscale Junctions: Effects of Electron-vibration Scattering and Local Heating
Bailey C. Hsu, Yu-Shen Liu, Sheng Hsien Lin +1
We report first-principles calculations of inelastic Seebeck coefficients in an aluminum monatomic junction. We compare the elastic and inelastic Seebeck coefficients with and with…
Counting Statistics in Nanoscale Junctions
Yu-Shen Liu, Yu-Chang Chen
We present first-principles calculations for moments of the current up to the third order in atomic-scale junctions. The quantum correlations of the current are calculated using th…
Atomic-scale Field-effect Transistor as a Thermoelectric Power Generator and Self-powered Device
Yu-Shen Liu, Hsuan-Te Yao, Yu-Chang Chen
Using first-principles approaches, we have investigated the thermoelectric properties and the energy conversion efficiency of the paired metal-Br-Al junction. Owing to the narrow s…
Effect of Thermoelectric Cooling in Nanoscale Junctions
Yu-Shen Liu, Bailey C. Hsu, Yu-Chang Chen
We propose a thermoelectric cooling device based on an atomic-sized junction. Using first-principles approaches, we investigate the working conditions and the coefficient of perfor…
