Abstract Thin polytetrafluoroethylene (PTFE) films are produced by deposition from a gas phase by two methods: electron‐enhanced vacuum deposition (EVD) and EVD + low‐temperature plasma (LTP). Structure, morphology, and composition of the films a

The influence of microwave radiation (2.45 GHz, 1.5 W cm−2, up to 80 s) on defects was studied in single crystals of n-6 H-SiC, n-GaAs, and epi-GaAs. The capture cross section of the charge carrier was found to change, and defect complexes were rec

Multilayer organic and inorganic systems of thin solid films are widely used in novel optoelectronic devices. The required properties of the system depend on the morphology of the films and transition zone at interfaces. We studied the formation of d
