Concerted Electrodeposition and Alloying of Antimony on Indium Electrodes for Selective Formation of Crystalline Indium Antimonide
The
direct preparation of crystalline indium antimonide (InSb)
by the electrodeposition of antimony (Sb) onto indium (In) working
electrodes has been demonstrated. When Sb is electrodeposited from
dilute aqueous electrolytes containing dissolved Sb<sub>2</sub>O<sub>3</sub>, an alloying reaction is possible between Sb and In if any
surface oxide films are first thoroughly removed from the electrode.
The presented Raman spectra detail the interplay between the formation
of crystalline InSb and the accumulation of Sb as either amorphous
or crystalline aggregates on the electrode surface as a function of
time, temperature, potential, and electrolyte composition. Electron
and optical microscopies confirm that under a range of conditions,
the preparation of a uniform and phase-pure InSb film is possible.
The cumulative results highlight this methodology as a simple yet
potent strategy for the synthesis of intermetallic compounds of interest
