Two-dimensional MoS electromechanical actuators
Nguyen T. Hung, Ahmad R. T. Nugraha, Riichiro Saito
We investigate electromechanical properties of two-dimensional MoS monolayers in the 1H, 1T, and 1T structures as a function of charge doping by using density function…
Universal curve of optimum thermoelectric figures of merit for bulk and low-dimensional semiconductors
Nguyen T. Hung, Ahmad R. T. Nugraha, Riichiro Saito
Analytical formulas for thermoelectric figure of merit and power factor are derived based on the one-band model. We find that there is a direct relationship between the optimum fig…
Three-dimensional carbon Archimedean lattices for high-performance electromechanical actuators
Nguyen T. Hung, Ahmad R. T. Nugraha, Riichiro Saito
We propose three-dimensional carbon (3D-C) structures based on the Archimedean lattices (ALs) by combining bonding in the polygon edges and bonding in the polygon ver…
Two-dimensional InSe as a potential thermoelectric material
Nguyen T. Hung, Ahmad R. T. Nugraha, R. Saito
Thermoelectric properties of monolayer indium selenide (InSe) are investigated by using Boltzman transport theory and first-principles calculations as a function of Fermi energy an…
Negative refraction in Weyl semimetals
M. Shoufie Ukhtary, Ahmad R. T. Nugraha, Riichiro Saito
We theoretically propose that Weyl semimetals may exhibit negative refraction at some frequencies close to the plasmon frequency, allowing transverse magnetic (TM) electromagnetic…
