| Laser induced plasma - a source of control of the properties of thin films (1993) | |||||||||||
Abstract | |||||||||||
| The temporal and spatial properties of laser-induced vapour and/or plasma involved in thin film deposition were investigated as a function of laser parameters (wavelength, power density distribution) and processing variables (target-substrate arrangement, superposed r.f. fields). The composition and ionization state of the vapour and plasma were measured by emission spectroscopy, and the geometry and dynamics of the vapour-plasma plume were measured by high-speed photography. The number and type of ionized species impinging on the growing films were varied in combination with the target-substrate arrangement to generate various film structures which are discussed with respect to applications. | |||||||||||
