Room temperature self-assembly of cation-free guanine quartet network nucleated from Mo-induced defect on decorated Au(111) with graphene nanoribbons
Amirreza Ghassami, Elham Oleiki, Dong Yeon Kim +3
Guanine-quadruplex, consisting of several stacked guanine-quartets (GQs), has emerged as an important category of novel molecular targets with applications from nanoelectronic devi…
Liquid-liquid-like phase transitions between high, mid, and low density phases in confined water
Saeed Pourasad, Amir Hajibabaei, Chang Woo Myung +1
Liquid-liquid phase transition (LLPT) in supercooled water has been a long-standing controversial issue. We show simulation results of real stable first-order phase transitions bet…
Anharmonicity-driven Rashba co-helical excitons break quantum efficiency limitation
Chang Woo Myung, Kwang S. Kim
Closed-shell light-emitting diodes (LEDs) suffer from the internal quantum efficiency (IQE) limitation imposed by optically inactive triplet excitons. Here we show an undiscovered…
La-Doped BaSnO Electron Transport Layer for Perovskite Solar Cells
Chang Woo Myung, Geunsik Lee, Kwang S. Kim
Due to the photo-instability and hysteresis of TiO electron transport layer (ETL) in perovskite solar cells (PSCs), novel electron transport materials are highly demanded. Here…
Nonstationary theory of magnetic field induced current for molecular spin nanojunction
M. Jouravlev, Kwang S. Kim
For the study of molecular spin junctions, we take into account two types of couplings between the molecule and the metal leads: (i) electron transfer that gives rise to net curren…
Carbon nanotube, graphene, nanowire, and molecule-based electron and spin transport phenomena using the non-equilibrium Green function method at the level of first principles theory
Woo Youn Kim, Kwang S. Kim
Based on density functional theory (DFT), we have developed algorithms and a program code to investigate the electron transport characteristics for a variety of nanometer scaled de…
