Surface modification of co-evaporated thin films upon oxygen and air exposure

Chemical and morphological characterizations of CoNi alloy nanoparticles formed by co-evaporation onto highly oriented pyrolytic graphite

“…Although such studies have been carried out for several decades, on substrates as varied as Si, Ga, As, Pt, Pd and highly oriented pyrolytic graphite (HOPG) [4][5][6][7][8][9], most of these studies were confined to pure metal NPs. Recently, bimetallic NPs have become an interesting research field due to certain properties of nanoscale alloys, which may exist in a number of structures and phases that are different from those of the corresponding bulk metals [10,11]. However, little has been reported on their chemical and morphological properties, particularly those of transition metal alloys.…”

Improved Removal Selectivity of Ruthenium and Copper by Glycine in Potassium Periodate (KIO4)-Based Slurry

“…These results are in agreement to the reported values. 20,21 After treating the Ru film in the 0.03 M KIO 4 -based solution for 5 min, the Ru 3d 5/2 and 3d 3/2 peaks shift to 280.6 and 284.6 eV, respectively, which correspond to the Ru XPS peaks in RuO 2 . 22 The intensity of the Ru 3d peak of the Ru film treated in the 0.03 M KIO 4 -based solution with 1 mM glycine increases compared to those from the Ru film treated in the 0.03 M KIO 4 -based solution only.…”
