Web11 Apr 2024 · However, when the thickness of the hBN film is in the range of 2–20 nm, the THF in the case of ε b = 4 exceeds that of ε b = 1. In particular, when the thickness is 3 nm, the THF is enhanced from 1.33 × 10 5 W/m 2 (ε b = 1) to 1.91 × 10 5 W/m 2 (ε b = 4). This suggests that a 1.43-fold larger THF is achieved when the permittivity of the ... Web11 Apr 2024 · Even on a per-thickness basis, MoS 2 is found to possess similar bending stiffness to hBN and is much stiffer than graphene. Density functional theory calculations suggest that this high bending rigidity of MoS 2 is due to its large interlayer thickness and strong interlayer shear, which prevail over its weak in-plane bonding. oxford alabama monthly weather
