ξ/ξ ratio versus the reciprocal size for different values of αshape 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 αshape values. The yellow region indicates the region where thermodynamics is no more valid
