摘要: We carried out an ab initio investigation of the charged states hydrogen in amorphous SiO2 using a previously generated model structure. found large variety equilibrium configurations as result disordered atomic structure our system. The formation energies H0, H+ and H- remain nevertheless close to energetics for α-quartz, with species always more stable than neutral one irrespective electron Fermi level.
