h-BN: Layer dependent macroscopic dielectric constant. a h-BN: In-plane macroscopic dielectric constant. b h-BN: out-of-plane macroscopic dielectric constant. ϵ∞ represents the macroscopic optical dielectric constant and ϵ0 represents the macroscopic static dielectric constant. The static out-of-plane dielectric constant varies from 3.29 (monolayer) to 3.76 (bulk). The in-plane static dielectric constant varies negligibly from 6.82 (monolayer) to 6.93 (bulk)
