Annotation The comparative study of gold nanoclusters phase formation processes in the matrix of poly-N-vinil-carbazole ( PVCa) at co-condensation from the gas phase in local electric field near the surface of the template and on the surface of neutral substrates is investigated. TEM studies have directly observed the golden critical nuclei in the PVCa matrix and determine their size. Experimentally proved that the size of the gold critical nuclei is 1.9 nm, whereas in the non-uniform electric field of the template is reduced it to 1.2 nm. Modelling the influence of polarization component on Au nucleation within the thermodynamic approach to electrically charged and neutral gold nanoclusters showed the possibility of the existence of the measured changes in the critical nucleus size in the field 108-1010 V/m.
