The main goal of this project is to develop methods for studying radiative properties of nano-objects deposited on a solid surface and testing of elaborated methods on those objects. The methods are implemented on the base of the scanning tunneling microscope equipped with a highly sensitive photodetector, the output of which (photon response) is proportional to the quantum yield of the tunneling area. Thus obtained maps of the distribution of the quantum yield of the surface attached to the atomic surface topography, ie, demonstrate the possibility of a photon scanning tunneling microscope (PSTM). The project focuses on the preparatory stages and phases of testing equipment for the implementation of the existing layout for the registration and processing of integrated photonic signal irradiated due to the interaction of tunneling current with nano-objects and analyzing the spectrum of this response, development and production samples of nanostructures and nano-objects covered with the organic molecules. Create the portable collapsible vacuum cell, which is equipped with electrodes for current-voltage characteristics measuring and the window for the registration of the optical emission from nano-objects that are in the microscopic gap between the electrodes. Assembled the data collection and reduction system of optical radiation emitted from these gaps, and develop the necessary software for this system. The approbation have made of the working model of the layout of the registration system for electroluminescence from nanostructures on samples of planar light-emitting device based on slot-type gold island films and nanocomposites consisting of gold island films covered by organic molecules of the phosphor. Designed and constructed a functional model of the system for nanopositioning, that has a maximum range of movement 50 ?m in the sample plane and up to 3 ?m in the perpendicular direction. Developed and implemented a method for manufacturing nano-backlash with atomic force microscope and tested ways to measure the width of the backlash. The possibilities of preparation nano-backlashs and two-dimensional nanostructures of arbitrary shape is demonstrated. To get the gold nanoparticles with controlled size and shape is proposed and tested microwave and thermal processing of gold films of different thicknesses, and the use nanosphere lithography, that can you get the gold nanoparticles wich size and shape are regulated with conditions of production and above modes of heat treatment. The recommendations on the use of these techniques is done.
