Preparation of ordered thin gold films

Gold nanolayer and nanocluster coatings induced by heat treatment and evaporation technique

“…A phenomenological study was carried out to find a reliable way for the gold thin film preparation. The following parameters have been focused on: annealing time of the substrate before deposition of the gold film, deposition rate of the gold film, substrate temperature before and during evaporation and annealing time after the deposition [20]. Deposition of Au films on mica with the deposition temperature 500°C led to the similar structures that we achieved on glass heated to 300°C, where pores and whiskers have been observed [20].…”

“…The influence of gold nanocluster formation has been also extensively studied [20] on mica. A phenomenological study was carried out to find a reliable way for the gold thin film preparation.…”

Surface-enhanced Raman spectral study of Au nano-particles/alkanethiol self-assembled monolayers/Au(111) heterostructures

“…Several reports have described the epitaxial growth of Au(1 1 1 ) on a cleaved-mica substrate [25][26][27][28], in which optimum deposition parameters for obtaining atomicallyflat domains of Au(1 1 1 ) are discussed. Because Raman scattering intensities of surface molecules depend strongly upon surface morphologies of the substrate, the epitaxial Au(1 1 1 ) surfaces fabricated under several deposition conditions are imaged by using AFM; Fig.…”

Molecular orientation of thiol-derivatized tetraphenylporphyrin on gold studied by XPS and NEXAFS

“…Then the gold films were flame-annealed in air. This is a well established technique to prepare a flat gold surface with (1 1 1) orientation [14][15][16][17]. Such gold films are commonly used as substrates for thiolate self-assembled monolayers [17][18][19].…”
