5.1. INTRODUCTION
Interest in thin-film formation processes dates at least to the 1920s. During research at the Cavendish Laboratories in England on evaporated thin films, the concept of formation of nuclei that grew and coalesced to form the film was advan[r]

There were obtained SRGs with a pitch of 250 nm and 1 µm, depending on the irradiation set-up. The modulation depth was between 10 nm and 800 nm, depending on the incident fluence/intensity and the number of subsequent incident pulses. The surface relief modulation time is of the order[r]

Nevertheless, prior to proceeding to this characterization, it is important to check the epitaxial relationship between the bottom electrode and PZT films.
Indeed, it must be kept in mind that the framework of this study is the fundamental understanding of the impact of crystal structure[r]

Polycrystalline Silicon Thin Film Transistors (poly-Si TFTs) have been played as important driving elements for Flat panel display (FPD). In this work, we studied crystallinities of laser-crystallized poly-Si thin films using Multi-Line Beam (MLB) –CLC and investigated the dependence of poly-Si thin[r]
