It is well known that the microstructural consequences of the ion implantation of semiconductor heterostructures can be severe: amorphisation of the damaged region is possible, and layer intermixing can result both from the original damage process and from the enhancement of the diffusion coefficients for the constituents of the original composition profile. A very large number of variables are involved (the atomic mass of the target, the mass and energy of the implant species, the flux and the total dose, the substrate temperature etc.) so that experimental data are needed despite the existence of relatively well developed models for the implantation process. A major difficulty is that conventional techniques (e.g. electron energy loss spectroscopy) have inadequate resolution for the quantification of any changes in the composition profile of fine scale multilayers. However we have demonstrated that the measurement of 002 dark field intensities in transmission electron microscope images of GaAs / AlxGa1_xAs heterostructures can allow the measurement of the local Al / Ga ratio.

This article explores the spatial dynamics of agrofuels. Building on categories from the field of critical spatial theory, it shows how these categories enable a comprehensive analysis of the spatial dynamics of agrofuels that links the macro-structures of the global political economy to concrete, place-based struggles. Four core socio-spatial dynamics of agrofuel politics are highlighted and applied to empirical findings: territorialization, the financial sector as a new scale of regulation, place-based struggles and transnational spaces of resources and capital flows.

Purpose. The purpose of the work is to analyze the application of the second and third parts of Article 3692 of the Criminal Code of Ukraine to officials in the context, that defines them by the Criminal Code of Ukraine in the note to Article 364 of the Criminal Code of Ukraine. Methodology. The methodology includes a comprehensive analysis and synthesis of the available scientific and theoretical material and the formulation of relevant conclusions and recommendations. In the course of the study, the following methods of scientific knowledge were used: terminological, logical-semantic, system-structural, logical-normative. Results: in the course of research the cause of criminalization of such act as "abuse of power" is considered, the subject of the specified criminal act which has the features of "an official" in the context, that defines it by the note to Article 364 of the Criminal Code of Ukraine is analyzed and the main ways of committing criminal acts, that are provided for in this article of the Criminal Code of Ukraine are identified. Originality. The study found, that one of the key conditions for the opportunity to influence officials, that are authorized to perform government or local self-government functions, is the position held by the official and the related opportunities. Therefore, taking into account the opinion of the scientists, that the subject of crimes, that are provided for by the second and third parts of Article 3692 is special, the peculiarities of which is the cumulative feature, that denotes, that such person is not endowed with the status of an official, well-founded need to specify the criminal legislation of Ukraine in terms of the application the second and third parts of Article 3692 of the Criminal code of Ukraine concerning officials in the context, that defines them by the criminal legislation of Ukraine in the note to Article 364 of the Criminal Code of Ukraine. Practical significance. The research results can be used in lawmaking in the improvement of anti-corruption legislation.
