The effects of applied potential, deposition time, and solution concentration on the morphology of the Au deposits are also discussed in our work.
By using a well-known electrochemical technique of under potential deposition and in situ redox replacement, sub-monolayer Au clusters are deposited onto Pt nanoparticle surfaces in a highly controlled manner, generating a unique surface alloy structure.
Also showing up as a potential deposition witnesses are Gary Rosenbach, Galleon's co-founder; Leon Shaulov, a top trader at the fund; Ian Horowitz, Raj Rajaratnam's personal trader; and Caryn Eisenberg, the former assistant to Raj Rajaratnam.
Scanning Electron Microscopy and UPD: Under Potential Deposition.
These samples were prepared by potentiostatic deposition at − 1.2 V (Fig. 6a), pulsed potential deposition with the on-time potential of − 1.5 V (Fig. 6b), and pulsed potential deposition with the on-time potential of − 1.8 V (Fig. 6c).
Textured ferromagnetic Fe nanowire arrays were electrodeposited using a rectangular-pulsed potential deposition technique into anodized aluminum oxide nanochannels.
In the under potential deposition process, the dominant deposition process is also at about -1.6 V.
Two dimensional (2D) clusters form preferentially on the terraces in the under potential deposition range.
It is well known that the crystalline orientation can be modified by deposition conditions such as the choice of potentiostatic and pulsed potential deposition [23].
Hence, we demonstrated that the rectangular-pulsed potential deposition technique can control the crystal orientation and aspect ratio of Fe nanowires, leading to excellent magnetic properties.
The degree of overpotential during the potentiostatic and the pulsed potential deposition significantly affected the crystal orientation and the magnetization performance of high aspect ratio Fe nanowire arrays.
