Laser irradiation of materials induces changes in their structure and functional properties.
In this work, lattice heating and electronic excitation on silver bromide (AgBr), provoked by femtosecond laser irradiation, have been investigated by finite-temperature density functional theory
and ab initio molecular dynamics calculations by using the two-temperature model. According to
our results, the electronic temperature of 0.25 eV is enough to excite the electrons from the valence
to the conduction band, whereas 1.00 eV changes the structural properties of the irradiated AgBr
material. Charge density simulations also show that an Ag clustering process and the formation of
Br3− complexes take place when the electronic temperature reaches 2.00 eV and 5.00 eV, respectively.
The present results can be used to obtain coherent control of the extreme nonequilibrium conditions
due to femtosecond laser irradiation for designing new functional materials. [-]
