Terahertz transitions in finite carbon chains
R. R. Hartmann, S. Kutrovskaya, A. Kucherik +2
We predict an optical effect associated with systems which exhibit topologically protected states separated by a finite distance. We develop a tight-binding model to calculate the…
Formation of Fractal Dendrites by Laser induced melting of Aluminum Alloys
Alexey Kucherik, Vlad Samyshkin, Evgeny Prusov +7
We report on the fabrication of fractal dendrites by laser induced melting of aluminum alloys. We target boron carbide (B4C) that is one of the most effective radiation-absorbing m…
Electric field assisted alignment of monoatomic carbon chains
Stella Kutrovskaya, Igor Chestnov, Anton Osipov +4
We stabilize monoatomic carbon chains in water by attaching them to gold nanoparticles (NPs) by means of the laser ablation process. Resulting nanoobjects represent pairs of NPs co…
Photosensitive free-standing ultra-thin carbyne-gold films
Vlad Samyshkin, Anastasia Lelekova, Anton Osipov +4
In the article we introduce the experiment of the photostimulation effect in the tunneling conductivity of free-standing thin C-Au films. We observe a sharp increase of the conduct…
The laser synthesis of linear carbon chains
Stella Kutrovskaya, Anton Osipov, Alexey Povolotskiy +4
We synthesize macroscopically long linear carbon chains (carbynes) in a colloidal solution, then deposit them on a surface. The method is based on the formation of carbon threads b…
