... unknown. By correlating macroscopic elastic constants with microscopic force constants of diamond-like structures, we here derived analytical expressions for the minimum Poisson’s ratio, the maximum Poisson’s ratio, and the Poisson’s ratios averaged by three schemes (i.e., Voigt averaging scheme, Reuss...
