Ab initio vibrations in nonequilibrium nanowires
We review recent results on electronic and thermal transport in two different quasi one-dimensional systems: Silicon nanowires (SiNW) and atomic gold chains. For SiNW’s we compute the ballistic electronic and thermal transport properties on equal footing, allowing us to make quantitative predictions for the thermoelectric properties, while for the atomic gold chains we evaluate microscopically ...
متن کاملAb initio study of ferroelectricity in BaTiO3 nanowires
We present a density-functional theory study of finite-size effects in stoichiometric and nonstoichiometric BaTiO3 nanowires of varying cross-sectional sizes and sidewall terminations. The tendencies for axial, transverse, and toroidal ferroelectric polarization instabilities in these nanowires have been characterized and possible driving forces underlying these behaviors have been identified. ...
متن کاملElectronic Structure of Silicon Nanowires Matrix from Ab Initio Calculations
An investigation of the model of porous silicon in the form of periodic set of silicon nanowires has been carried out. The electronic energy structure was studied using a first-principle band method-the method of pseudopotentials (ultrasoft potentials in the basis of plane waves) and linearized mode of the method of combined pseudopotentials. Due to the use of hybrid exchange-correlation potent...
متن کاملAB INITIO QUANTUM CHEMICAL STUDIES IN CTAB
Quaternary ammonium compounds (QACS) are employed both as disinfectants for manual processing lines and surfaces in the food industry, and in human medicine area. QACS also cause cell death by protein denaturation . One of the QAC is cetyl trimethyl ammonium bromide (CTAB) that appears to rapture the cell membrane. The primary site of action of CTAB has been suggested to be the lipid components...
متن کاملJust How Ab Initio Is Ab Initio Quantum Chemistry?
Quantum Mechanics has been the most spectacularly successful theory in the history of science. As is often mentioned the accuracy to which the gyromagnetic ratio of the electron can be calculated is a staggering nine decimal places. Quantum Mechanics has revolutionized the study of radiation and matter since its inception just over one hundred years ago. The impact of the theory has been felt i...
