Black, red and green points refer to the calculated values of the vacancy formation energy (as a function ofγ0(θ)) for Au NCs on SiO2 with diameter of D = 2.5, 3.5, 7 nm, respectively. Blue, cyan and magenta points refer to the calculated values of the vacancy formation energy (as a function of γ0(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
