脉冲激光沉积 (Pulsed laser deposition, PLD),就是将激光聚焦于靶材上一个较小的面积,利用激光的高能量密度将部分靶材料蒸发甚至电离,使其能够脱离靶材而向基底运动,进而在基底上沉积,从而形成薄膜的一种方式。 在众多的薄膜制备方法中,脉冲激光沉积技术的应用较为广泛,可用来制备金属、半导体、氧化物、氮化物、碳化...

Chapter 3 – Pulsed laser deposition of oxides 29 CHAPTER 3 PULSED LASER DEPOSITION OF OXIDES 3.1 Introduction As a materials processing technique, laser ablation was utilized for the first time in the 1 1960s, after the first commercial ruby laser was invented . Nevertheless, as a thin film ...
Further on pulsed laser deposition is presented as an alternative way to control layer by layer growth. First results concerning the island density in the sub-monolayer regime are shown.关键词: thin films pulsed-laser deposition substitution effects critical current density TmBaSrCu3O7-delta GdBaS...
Pulsed laser depositionHeterojunctionsIn this paper pulsed laser deposition (PLD) methods are used to study p-n CdTe/CdS heterojunctions fabricated in-situ. In-situ film deposition allows higher quality p-n interfaces by minimizing spurious contamination from the atmosphere. Morphologic and structural ...
