Abstract:
The possibility of obtaining new materials as a result of tunneling chemical reactions that occur on the surfaces of compressible nanoparticles is shown. The chemical bonds of surface atoms can be excited. Silicon nanoparticles covered with hydrogen atoms are used as a model. Quantum tunneling of hydrogen atoms of different nanoparticles towards each other takes place under the branches of two intersecting parabolas. A semiclassical approach is chosen for simulation. The branches of the parabolas are directed upwards. In compressed nanoparticles, the pressure at the points of their contact can increase by a factor of a few hundred or even a few thousand. Free bonds that appear after hydrogen detachment transform into chemical bonds between nanoparticles.
