Influence of solvent polarization and non-uniform ionic size on electrokinetic transport in a nanochannel
Jun-Sik Sin, Nam-Hyok Kim, Chol-Ho Kim +1
In this paper, we study the electroosmotic transport in a nanofluidic channel by using a mean-field theory accounting for non-uniform size effect and solvent polarization effect. W…
Electric double layer of colloidal particles in salt-free concentrated suspensions including non-uniform size effects and orientational ordering of water dipoles
Jun-Sik Sin, Kwang-Il Kim, Kuk-Chol Ri +3
The response of a suspension under a variety of static or alternating external fields strongly depends on the equilibrium electric double layer that surrounds the colloidal particl…
Effect of solvent polarization on electric double layer of a charged soft surface in an electrolyte solution
Jun-Sik Sin, Nam-Hyok Kim, Chung-Sik Sin
We study the electric double layer near a charged soft surface by using a mean-field approach including non-uniform size effect and solvent polarization. Based on a free energy mod…
Influence of halide composition on the structural, electronic, and optical properties of mixed CHNHPb(IBr) perovskites calculated using the virtual crystal approximation method
Un-Gi Jong, Chol-Jun Yu, Nam-Hyok Kim +1
We investigate the structural, electronic and optical properties of mixed bromide-iodide lead perovskite solar cell CHNHPb(IBr) by means of the virtual crys…
study of the adsorption and dissociation of nitrogen molecule on Fe(111) surface
Myong-Song Ryang, Nam-Hyok Kim, Song-Jin Im
The adsorption and dissociation of nitrogen molecule on Fe(111) surface is studied by density functional theory calculations. The simulation results show that the molecule needs to…
First-principles study on electron field emission from nanostructures
Hyon-Chol Choe, Nam-Hyok Kim, Hyok Kim +1
A first-principles approach is introduced to calculate electron field emission characteristics of nanostructures, based on the nonequilibrium Green function technique combined with…
New discrete method for investigating the response properties in finite electric field
Myong Chol Pak, Nam-Hyok Kim, Hak-Chol Pak +1
In this paper we develop a new discrete method for calculating the dielectric tensor and Born effective charge tensor in finite electric field by using Berry's phase and the gauge…
