Abstract Microelectrodes are used to extract thermodynamic, transport, and kinetic data for the gallium trichloride/1‐methyl‐3‐ethylimidazolium chloride room‐temperature molten salt that has been used by the authors to form GaAs thin films. The gallium electrodeposition process, which must be understood for the analysis of the GaAs deposition process, is simulated numerically. A plausible gallium deposition mechanism is identified. Microcylinder electrodes are shown to be advantageous for the acquisition of physicochemical constants. Microdisk electrodes are employed to investigate current oscillation phenomena that appear to be related to metal crystallization processes.
