The determination of small variations in the stoichiometry of undoped, semi-insulating gallium arsenide can be achieved by using constant current coulometly. Samples taken from a wafer are etched in HF, dissolved in NaOH-peroxide solution, then treated with a citric acid buffer. To convert the arsen
