“…There has been very little work reported on the electrochemistry of hydrocarbons and of antimony in such highly acidic media, especially that dealing with Sb(III)/Sb(V) couple. Most of the relevant work to be found in the literature concerns the reduction of Sb(III) in conventional acid solutions to form Sb(O), and the further reduction of the metal to stibine (SbH~) (14)(15)(16)(17)(18)(19)(20). A few reports have discussed the electrochemical reduction of Sb(V), which undergoes a 5-electron reduction directly to Sb(O).…”

The electrochemistries of antimony and simple hydrocarbons were examined in HF/SbF5 . From cyclic voltammetric data, Sb(V) appears to be a strong oxidizing agent in the super acid media, capable of oxidizing hydrocarbons containing three or more carbon atoms. It is therefore reasonable that the Sb(V) reduction process supplies the energy required for the super acid “catalyzed” condensation of saturated hydrocarbons, confirming suggestions already in the literature. The anodic oxidation of aromatic hydrocarbons was also examined in acidic fluoride media ( HF/SbF5 and HF/normalNaF ). It is observed that the oxidation of benzene results in the deposition of electronically conducting polymeric material on the anode. The material has been identified as p‐polyphenylene. The conductivity of the polymer is assumed to result from the formation of a charge‐transfer complex between the partially oxidized polymer and the Lewis acid.

This chapter concerns the state of development of electrochemical atomic layer epitaxy (EC‐ALE), the electrochemical analog of atomic layer epitaxy (ALE). EC‐ALE is being developed as a methodology for the electrodeposition of compound semiconductors with nanoscale control. ALE is based on the formation of compounds, one monolayer (ML) at a time, using surface‐limited reactions. An atomic layer of one element can be electrodeposited at a potential under that needed to deposit the element on itself, and this process is referred to as underpotential deposition (UPD). EC‐ALE is the use of UPD for the surface‐limited reactions in an ALE cycle. Electrodeposition is generally performed near room temperature, avoiding problems with interdiffusion and mismatched thermal expansion coefficients. This makes EC‐ALE a good candidate to form superlattices, where the compound deposited is modulated on the nanometer scale. This chapter describes the basics of the EC‐ALE cycle, the elements that have been used to form deposits, as well as the solutions, rinsing, and potential changes. It describes the hardware presently being used by this group and other research laboratories, the compounds that have been formed, and the development of deposition cycles for various compounds. It describes the status of device formation using EC‐ALE, and goes over some of the problems and issues involved in developing cycles and growing films. Finally, given that EC‐ALE is based on surface‐limited electrochemical reactions, studies of relevant electrodeposit surface chemistry are discussed.
