Laser-induced structural phase transition in a PbI2 single crystal
Bibik V. A. , Blonskii I. V., Brodin M. S., Davydova N. A.
A structural phase transition between polymorphic modifications of a layered Pbl2 crystal has been induced at room temperature by a laser beam for the first time. The transition is from a state with a higher free energy to one with a lower free energy.
