Black, red and green points refer to the calculated values of the cohesive energy (as a function of γ ₀ (θ)) for Au NCs on SiO₂ with diameter ofD = 2.5, 3.5, 7 nm, respectively. Blue, cyan and magenta points refer to the calculated values of the cohesive energy (as a function ofγ ₀(θ)) for Au NCs in SiO₂with diameter ofD = 2.5, 3.5, 7 nm, respectively. The calculations are performed using , , , q = 0.1 for the Au NCs on SiO₂ and q = 1 for the Au NCs in SiO₂
