Ab-initio modeling of Al2O3 lattice instability under extreme excitation of the electronic system
Original language description
Nonthermal phase transformations induced in Al2O3 by the electronic temperatures above similar to 2.5 eV is demonstrated with ab initio molecular dynamics simulations. When this temperature exceeds similar to 4 eV, such a transformation occurs within similar to 500 fs i.e. within the typical time-scale of relaxation of the excited electronic system in a micron-size spot of a femtosecond-laser pulse. The electronic temperature at least above 6-10 eV is required for a nonthermal melting to occur in Al2O3 within similar to 50-100 fs, which is the time scale of cooling down of the electronic system in a swift heavy ion track. Because such level of the electronic temperature cannot be kept during all this time, we conclude that nonthermal melting of alumina in SHI tracks is implausible.
