結(jié)果,HPPMS涂層應(yīng)具有改善的摩擦學(xué),光學(xué),電學(xué)和環(huán)境性能。改善的微結(jié)構(gòu)也改善了光學(xué)性能[3,4,5-9]。眾所周知,折射率取決于光學(xué)涂層的密度。密度較小的涂層的折射率通常低于密度較高的涂層。TiO 2涂層是依賴于密度的完美例子。這種材料的折射率可以在2.2 – 2.5之間變化,具體取決于密度。據(jù)報(bào)道,與直流磁控濺射膜相比,由HPPMS沉積的膜具有較高的折射率,如圖1所示[5]。在整個(gè)光譜上折射率較高。這些涂層的密度也為3.83 g / cm 3DC膜的密度為3.71 g / cm?3,表面粗糙度為1.3 nm,表面粗糙度僅為0.5 nm?。如果使用電源的最佳占空比,則TiO?2涂層的折射率也很高,約為2.72?[3]。改善SiO?2,ZnO,Al?2?O?3,Ta?2?O?5和ZrO?2的光學(xué)性能電影也有報(bào)道[6,7,8]。這些結(jié)果令人印象深刻,但必須注意某些事項(xiàng)。與使用其他電源沉積的涂層相比,HPPMS涂層并不總是具有改進(jìn)的性能[10]。光學(xué)常數(shù)總是在很大程度上取決于沉積條件,并且必須為每種材料和沉積系統(tǒng)確定最佳的一組條件。我看到平面磁控濺射膜也報(bào)道了很高的折射率。實(shí)際上,在某些情況下,中頻磁控濺射比HPPMS具有更好的性能[8]。
