Abstract

The crystallization behaviour of Ni doped magnetron co-sputtered amorphous silicon thin films (MSP-a-Si(Ni)) has been investigated by means of near infrared-visible-ultraviolet (NIR-VIS-UV) transmission spectroscopy, transmission electron microscopy (TEM) and scanning transmission electron microscopy (STEM). Using the change in optical transmission spectra of crystallized a-Si(Ni) thin films the crystallization kinetics is described. At the crystallization frontier a needle morphology of single crystals is observed with STEM, which is followed by solid state diffusion of nickel through the amorphous matrix. Using a long term thermal treatment we have studied the formation of expansed monocrystalline networks.
