Influence of laser conditioning on defects of HfO_2 monolayer films
Influence of laser conditioning on defects of HfO_2 monolayer films
摘要
The influence of laser conditioning on defects of HfO2 monolayer films prepared by electron beam evaporation （EBE） is investigated utilizing the spot-size effect of the laser-induced damage.It is found that the laser-induced damage threshold of HfO2 monolayer films can be increased by a factor of 1.3-1.6.It is also found that the defects with low threshold can be removed by laser conditioning and defects with higher threshold may be removed partially.
