Isotermal desorption of impurity matrix atoms (as CO, CO₂, H₂, H₂O) out os sapphire bulk has been studied. A theoretical model has been proposed for diffusion mechanism of the atoms included in gas-vacancy complexes 2Vᶦ-Mᶦ (Mᶦ being an atom, Vᶦ, a neutral vacancy). According to the model, the gas-va...
