FIELD: electrical engineering.
SUBSTANCE: invention may be used for production of individual crystals of zinc oxide and arrays thereof for application as active elements, material for photocatalytic water treatment, piezoelectric sensors as well as for fundamental physical studies of crystal growth kinetics. Crystals are grown in the air using a continuous action ytterbium fibre laser with yellow metal surface with a layer of multi-walled carbon nanotubes applied thereon treated with such laser radiation with power density equal to approximately 105 W/cm2 during 10 sec. The method enables production of micro- and nanostructured zinc oxide arrays consisting of filamentary crystals, microplates and druses.
EFFECT: invention enables crystals production without special catalysts or crystallisation chambers.
