Strength of effective Coulomb interaction in two-dimensional transition-metal Halides MX${}_2$ and MX${}_3$ (M=Ti, V, Cr, Mn, Fe, Co, Ni; X=Cl, Br, I)

We calculate the strength of the effective onsite Coulomb interaction (Hubbard $U$) in two-dimensional (2D) transition-metal (TM) dihalides MX${}_2$ and trihalides MX${}_3$ (M=Ti, V, C…
