Stacking Polymorphism of PtSe $_{2}$ : Its Implication to Layer-dependent Metal-insulator Transitions

Jeonghwan Ahn, Iuegyun Hong, Gwangyoung Lee +4

Using diffusion Monte Carlo (DMC) and density functional theory (DFT) calculations, we examined the structural stability and interlayer binding properties of PtSe $_{2}$ , a representa…

Exploring interlayer coupling in the twisted bilayer PtTe $_{2}$

Jeonghwan Ahn, Seoung-Hun Kang, Mina Yoon +1

We have investigated interlayer interactions in the bilayer PtTe $_{2}$ system, which influence the electronic energy bands near the Fermi levels. Our diffusion Monte Carlo (DMC) ca…

Commensurate-incommensurate solid transition in the $^{4}$ He monolayer on $γ$ -graphyne

Jeonghwan Ahn, Hoonkyung Lee, Yongkyung Kwon

Path-integral Monte Carlo calculations have been performed to study the $^{4}$ He adsorption on $γ$ -graphyne, a planar network of benzene rings connected by acetylene bonds. Assuming…
