The purpose of this paper is to substantiate the necessity and technical possibilities of creating a coherent and intelligent digital tool for small and medium-sized enterprises’ (SME) segmentation, with the support of regional development agencies’ (RDAs) databases. This tool would allow RDAs to improve the monitoring of the financial and innovati...

We show that the thermal decomposition of SiC (0001) surface is reversible, if carried out in near-equilibrium conditions, with an external Si atomic beam applied to the substrate. Taking advantage of this observation we design a novel process, allowing for the growth of uniform, few-layers, ABC-stacked graphene. This process is composed of two pha...

We have performed a study of thermal graphitization of SiC (0001) surface in the high-purity molecular beam of Si atoms obtained from a controllable source. With the aid of Si beam, we have been able to achieve the semi-equilibrium reaction conditions and to control the growth rate of graphene film freely until complete stop of the graphitization,...

We study the properties of the InSb (001) surface covered with ultrathin KBr films, with a thickness of 1 to 4 ML. KBr deposition does not strongly perturb the crystallographic structure of the InSb surface and the electronic structure of the substrate also remains unaffected by the overlayer. A simple model of the studied system is proposed, in wh...

We have studied the properties of the InSb (100) surface passivated with sulfur dimers emitted by the solid-state electrochemical cell in ultra-high vacuum. Annealing the passivated surface in the temperature equal to T = 326 °C led to the formation of the c(4 × 8) surface reconstruction, while increasing the temperature to T = 348 °C resulted in t...
Article
Two dimensional electron gases (2DEGs) at surfaces and interfaces of semiconductors are described straightforwardly with a 1D self-consistent Poisson-Schr\"{o}dinger scheme. However, their band energies have not been modeled correctly in this way. Using angle-resolved photoelectron spectroscopy we study the band structures of 2DEGs formed at sulfur...
Article
We reproduce the experimentally observed polymorph stability of the tetramorph pyrazinamide using periodic density functional theory (DFT) calculations augmented with an empirical dispersion term. This was only possible using highly accurate experimental structures, including a model of a disordered polymorph. Further, we demonstrate that a large b...
