Interplay of the disorder and strain in gallium oxide

Autor: Azarov, Alexander, Venkatachalapathy, Vishnukanthan, Karaseov, Platon, Titov, Andrei, Karabeshkin, Konstantin, Struchkov, Andrei, Kuznetsov, Andrej

Publikováno v: Scientific Reports 12, 15366 (2022)

Ion irradiation is a powerful tool to tune properties of semiconductors and, in particular, of gallium oxide (Ga2O3) which is a promising ultra-wide bandgap semiconductor exhibiting phase instability for high enough strain/disorder levels. In the pre

Report

Effect of the surface shape of a large space body on its fragmentation in a planetary atmosphere

Autor: Khrennikov, Daniil E., Titov, Andrei K., Ershov, Alexander E., Klyuchantsev, Andrei B., Pariev, Vladimir I., Karpov, Sergei V.

Publikováno v: Mon. Not. Roy. Astron. Soc., 493 (2020) 1352-1360

Employing the finite element and computational fluid dynamics methods, we have determined the conditions for the fragmentation of space bodies or preservation of their integrity when they penetrate into the Earth's atmosphere. The origin of forces co

Report

On the possibility of through passage of asteroid bodies across the Earth's atmosphere

Autor: Khrennikov, Daniil E., Titov, Andrei K., Ershov, Alexander E., Pariev, Vladimir I., Karpov, Sergei V.

Publikováno v: MNRAS, 493 (2020), 1344

We have studied the conditions of through passage of asteroids with diameters 200, 100 and 50 m, consisting of three types of materials -- iron, stone and water ice across the Earth's atmosphere with the minimum trajectory altitude 10--15 km. The con

Peculiarities of structure damage accumulation under the implantation of ions of different masses into alpha-gallium oxide at low damage levels

Autor: Klevtsov Anton, Karaseov Platon, Karabeshkin Konstantin, Titov Andrei

Publikováno v: St. Petersburg Polytechnical University Journal: Physics and Mathematics, Vol 16, Iss 4 (2023)

In the paper, the distributions of structure damage created in alpha-phase of gallium oxide by keV fluorine, phosphorus and xenon ion irradiation, have been obtained at room temperature. A noticeable effect of the average individual collision cascade

Size effects in molecular dynamics simulations of a fullerene ion impact on the silicon surface

Autor: Karasev Kirill, Strizhkin Denis, Karaseov Platon, Titov Andrei

Publikováno v: St. Petersburg Polytechnical University Journal: Physics and Mathematics, Vol 16, Iss 4 (2023)

In the paper, the interaction of an accelerated C60 fullerene ion with silicon monocrystal surface has been studied using molecular dynamics simulation. The dependence of a resulting crater size and sputtering yield on the initial size of the target
