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

Jeonghwan Ahn, Hoonkyung Lee, Yongkyung Kwon

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