Quasiparticle band structures, spontaneous polarization, and spin-splitting in noncentrosymmetric few-layer and bulk -GeSe
Han-gyu Kim, Hyoung Joon Choi
Group-IV monochalcogenides have attracted much attention due to their potential of ferroelectric and multiferroic properties. Recently, centrosymmetric gamma-phase GeSe in a double…
Quasiparticle band structures of bulk and few-layer PdSe2 from first-principles GW calculations
Han-gyu Kim, Hyoung Joon Choi
We performed first-principles density functional theory (DFT) and GW calculations to investigate electronic structures of bulk and few-layer PdSe2. We obtained the quasiparticle ba…
Single-Crystalline Metallic Films Induced by van der Waals Epitaxy on Black Phosphorus
Yangjin Lee, Han-gyu Kim, Tae Keun Yun +11
The properties of metal-semiconductor junctions are often unpredictable because of non-ideal interfacial structures, such as interfacial defects or chemical reactions introduced at…
Thickness dependence of work function, ionization energy, and electron affinity of Mo and W dichalcogenides from DFT and GW calculations
Han-gyu Kim, Hyoung Joon Choi
Transition-metal dichalcogenides (TMDs) are promising for two-dimensional (2D) semiconducting devices and novel phenomena. For 2D applications, their work function, ionization ener…
