FIELD: electricity.
SUBSTANCE: method of etching of monocrystals is performed in vapours of the mix containing 1 volume part of fluoric and 2 volume parts of nitric acid, while monocrystals are placed above a ceramic crucible or a plastic cup with the mix of acids heated from the room temperature up to 60-70°C within 7-10 minutes. By effect of vapours of mix the domain and dislocation structures in samples are revealed.
EFFECT: improvement of safety and environmental friendliness of process.
