Self-organized submicron fibers in single crystal from high temperature elaboration

Photonic crystal-like material synthesized by self-organization

“…The composition of the crystalline structure and the fibers were confirmed by chemical analysis. And that the fibers are glassy was confirmed by the Raman measurements, which we reported earlier [9]. The 'floating zone method', that we used here, makes it possible to obtain crystals of great dimension and high quality [10].…”

“…Even though the size and spacing becomes smaller with increasing rate, it becomes more disordered. Therefore, we fixed this value at 1.3 mm/h and it was possible to obtain single crystals of about 14-cm long [9]. The optimum growth rate varies with the composition, stoichiometry, etc.…”

“…Therefore, it is the compromise between the Si content and the growth rate that acts as the limitation to the minimum fiber size and spacing obtainable by this method. By working at slightly over stoichiometric composition, we are able to reduce this size up to 0.5 mm with spacing as small as 1.3 mm [9].…”

A novel surface plasmon resonance enhanced total internal reflection ellipsometric application: electrochemically grafted isophthalic acid nanofilm on gold surface

“…13 Metal and carbon surface nanofilm modification studies such as self-assembled monolayers (SAMs), diazonium salts reduction, Langmuir-Blodgett films and layer-by-layer surface modifications have gained more interest in recent years. [14][15][16][17] Metal surface modifications by electrochemical techniques are important due to imparting novel and specific properties to the interfaces. A modified surface provides new applications, for instance in sensor researches, surface functionalization studies, chemical and electrochemical analysis, 18 corrosion, 19 molecular electronics.…”
