The comparative study of the preparation of carbon films by the methods of direct and inverse femtosecond laser deposition in the nitrogen atmosphere is performed for the first time. It is found that the surface of the film prepared by the method of

Vaporisation from rough surface areas during the laser ablation of foam graphite under vacuum generates a shock wave of recoil pressure of the vaporised substance which destroys the layer heated by radiation by desorbing large fragments from the mate

A procedure was developed for preparing bulk carbon nitride crystals from an amorphous nitrogen- and carbon-containing material at ultrahigh pressures and temperatures in the presence of seeds of crystalline C3N4 films prepared by a laserelectric dis

A study of the thermodynamics of laser evaporation of amorphous carbon nitride makes it possible to predict the optimum conditions for the laser deposition of crystalline films of superhard carbon nitride.

Ionisation of lanthanum monoxide molecules by a two-step scheme, in which the first-step radiation transfers a molecule into an excited electronic state, and the second-step radiation excites the molecule to the ionisation potential, is proposed; thi

Laser ablation of a foam graphite foil is governed by the splitting off of 'cold' weakly bound layers (stacks) of crystallites following the recoil pulses of the thermal vaporisation of the material.

The change in recoil pressure of polycrystalline graphite as the radiation intensity increases during laser pulse evaporation is related to the movement of the surface as a dynamic system along the curve of the liquid-vapour equilibrium above the tri

When applying to the probing electrode the potentials with the different polarity one can notice that the non-selective and selective signals behave quite differently. In case of the positive potential compared with the negative one the non-selective
