The paper includes an overview of main technical observations and crucial experiments which prove the electron corpuscular nature and led at the start of 20th century towards its mass and charge values determination.
Processes of lead sulfide film forming from aqueous solutions are considered. Two main stages of such film growth are highlighted. It is shown that the first stage can be used to produce arrays of lead sulfide quantum dots.
At paper, LEDs, based on the solid solution of system AlGaInN with super-lattices, were explored. Basic parameters and characteristics were found. Solid solution compound of nitrides is selected to provide work at blue visible range. For comparison of parameters and characteristics metrological research was conducted with the simple solid solution as the blocking of the upper layer. Special design...
This article discusses the issues relating to the switching and memory processes in thin films structures based on Me-MeOx-Me systems, also referred to as memristor. The memristor creation allows associative computing architecture hardware realized by synapse from nano-materials copying and the neuromorphic microchips and computing devices. As a result, programmable computers history completion and...
Cadmium sulfide thin films have been deposited by successive ionic layer adsorption and reaction method from ethanol-aqueous solutions. The films were deposited on glass substrates. The cadmium sulfide films have been characterized by transmission spectra. Thicknesses of layers were found by AFM microscopy of partially etched film.
Nanoparticles of porous silicon were obtained by electrochemical anodic etching. Morphology and internal structure of porous silicon powders were investigated by scanning electron microscopy. The influence of technological conditions of post-processing on morphology and internal structure is discussed.
Zinc oxide nanowires were grown by the hydrothermal method on nanocomposite layers of zinc oxide and silicon dioxide prepared by the sol-gel method with different composition. The morphology of samples and seed layers were studied by scanning electron microscopy and atomic force microscopy.
Many groups of engineers and researchers worldwide are involved in the application-oriented development of sensors. These efforts are often triggered by industrial applications and their extraordinary requirements in durability and reliability. Typical products are highly specialized sensors e.g. for temperature which are exposed to high physical and chemical stresses like in cutting or forming processes...
The majority of published microoptical gyro prototypes employ of the planar single-mode resonators of this or that configuration (single ring, multi-ring, spiral etc.). Whispering gallery modes resonators can be used as the gyro sensitive element instead of planar single-mode resonator. In this work we will consider effects arising in the whispering gallery modes resonator during its rotation and...
A mathematical model describing the process of emission output of the LEDs and devices on their basis. The model is based on the corpuscular Monte Carlo method. Within the model, the study of the effect of the geometry of the structure on the light output of the LED light in the blue range was produced. Special attention is given to the influence of texturing interfaces on the process of the light...
Perlite is used several applications on building construction for heat and sound insulation, on agriculture and greenhouse for Alter purposes. The aim of this study is to investigate the usability of perlite coated polyester fabric to see the thermal insulation applications. Polyester nonwoven with 180g/m2 weight was coated with four different particle size perlite stone powders. The expanded perlite...
The study results of template-based field emission hexagonal silicon carbide 6H-SiC<N> cathodes with micro-shaped surface covered with thin CVD-deposited nanocrystalline diamond layer are presented below. The current-voltage characteristics of 6H-SiC cathodes with non-doped and boron-doped diamond layers were experimentally obtained. The study touches upon the issue of inhomogeneity factors...
