High-field NMR spectroelectrochemistry of spinning solutions: simultaneous in situ detection of electrogenerated species in a standard probe under potentiostatic control

Epitaxial growth of PbSe is addressed on (111) InP single crystals by electrodeposition from aqueous solutions containing Se(IV), Pb(II) and Cd(II). The structure of the deposits is studied by reflection high-energy electron diffraction and X-ray diffraction. It is shown that an epitaxial growth is only observed in the presence of cadmium in the electrolyte. The best epitaxy is obtained for an optimal 0.5 M cadmium concentration.
