Nonlinear Optical Response of Sb80Bi20 Phase Change Films

Ultrafast dynamics of BixSb1-x film studied by femtosecond pump–probe technique

“…Recently, nonlinear optical response of transmittance and reflectance of the film is investigated using a confocal Zscan technique with a continuous wave He-Ne laser. The experimental results indicated that the BiSb film has a good opto-thermal stability and demonstrates capability for phase change data storage [15]. However, the ultrafast carriers dynamics of Bi x Sb 1-x has not been studied by the femtoscond pump-probe technique, to the best of our knowledge.…”
