ξ/ξ_∞ ratio versus the reciprocal size for different values of α_shape parameter. When D⁻¹ is equal to 0 (vertical red line) or when ξ/ξ_∞ is equal to 1 (horizontal red line) then there is no size effect, and the material behaves as the bulk one. The solid,dashed and dotted black(blue)lines indicate the behavior of “fermionic” (“bosonic”) nanomaterials properties for different α_shape values. The yellow region indicates the region where thermodynamics is no more valid
