No full textLe ZC, Dreeskornfeld L, Rahn S, Segler R, Kleineberg U, Heinzmann U. Application of reactive ion etching to the fabrication of microstructure on Mo/Si multilayer. CHINESE PHYSICS LETTERS. 1999;16(9):665-666.Mo/Si multilayer mirrors (30 periods, doublelayer thickness 7nm) with the AZ-PF514 resist pattern whose smallest lines and spaces structure was 0.5 mu m were etched by reactive ion etching (PIE) in a fluorinated plasma. The etch rate, selectivity and etch profile were investigated as a function of the gas mixture, pressure, and plasma rf power. The groove depth and the etch profile were investigated by an atomic force microscope before RIE, after RIE and after resist removal

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
