tively smooth and homogeneous in cross-section without ap-parent pinholes (Figure 1b). Compositional analysis by mass spectrometry identified the deposition of both vanadium and bismuth with a 2.01:1 ratio of V:Bi (Table 1). The significant 33.2 at% Bi in the film was a clear sign of a catalytic effect of aV 2O 5 surface to induce deposition of BiPh 3. The metal pulsing ratio was ...

Electrodeposition of bismuth from nitric acid electrolyte

Bismuth deposition was determined to be quasi-reversible on Au, with a current efficiency of 100%, based on integration of deposition and stripping voltammetric waves. No interference from nitrate reduction was found on Bi and Au, whereas nitrate reduction occurred on W and Cu electrodes. Analysis of current-time transients clearly shows nucleation on Au to be instantaneous. Field emission ...

2012-10-09· This involves post-deposition heating to 260°–270° for ten hours of a bismuth thin film sputter-deposited at room temperature onto an oxide film on a Si(1 0 0) substrate. The heating induces stress in the film which is relaxed by extrusion of nanowires normally to the film. The time-scale of this is much longer than that used here and the substrates were pre-etched to remove the oxide.
