Manifestation of the thermoelectric properties in Ge-based halide perovskites
Un-Gi Jong, Chol-Jun Yu, Yun-Hyok Kye +2
In spite of intensive studies on the chalcogenides as conventional thermoelectrics, it remains a challenge to find a proper material with high electrical but low thermal conductivi…
Molecular dynamics study of the effect of moisture and porosity on thermal conductivity of tobermorite 14 Å
Song-Nam Hong, Chol-Jun Yu, Kum-Chol Ri +2
The effect of moisture and porosity on thermal conductivity of tobermorite 14 Å~as the major component of cement paste is studied by using molecular dynamics simulation with ClayFF…
Thermal conductivity of porous jennite by molecular dynamics method
Song-Nam Hong, Chol-Jun Yua, Un-Song Hwang +2
The thermal conductivity of porous jennite, as the major component of cement paste, and its porosity and temperature dependences are simulated by molecular dynamics methods using C…
First-Principles Study on NaxTiO2 with Trigonal Bipyramid Structures: An Insight into Sodium-Ion Battery Anode Application
Song-Hyok Choe, Chol-Jun Yu, Kum-Chol Ri +4
Developing efficient anode materials with low electrode voltage, high specific capacity and superior rate capability is urgently required on the road to commercially viable sodium-…
The maximum interbubble distance in relation to the radius of spherical stable nanobubble in liquid water: A molecular dynamics study
Song-Nam Hong, Song-Hyok Choe, Un-Gi Jong +2
The mechanism of superstability of nanobubbles in liquid confirmed by many experimental studies is still in debate since the classical diffusion predicts their lifetime on the orde…
Revealing the stability and efficiency enhancement in mixed halide perovskites MAPb(ICl) with ab initio calculations
