Near-Infrared Femtosecond Laser for Studying the Strain in <formula formulatype="inline"> <tex Notation="TeX">$\hbox{Si}_{1\hbox{-}{\rm x}}\hbox{Ge}_{\rm x}$</tex></formula> Alloy Films via Second-Harmonic Generation

The second-harmonic generation (SHG) from Si<sub>1-x</sub>Ge<sub>x</sub> alloy films has been investigated by near-infrared femtosecond laser. Recognized by s-out polarized SHG intensity versus rotational angle of sample, the crystal symmetry of the fully strained Si<sub&g...
