This paper reports the study of Ge<inf>y</inf>Si<inf>1&#x2212;y</inf>:H films deposited at temperatures in the range of T<inf>d</inf>= 70 to 300 &#x00B0;C. The films were grown in capacitive low-frequency (f=110 KHz) discharge from Si:H<inf>4</inf> and Ge:H<inf>4</inf> feed gases diluted with H<inf>2</inf>. Other parameters were as follow: hydrogen flow(More)
In this work we study the atomic composition in SiGe:H films as a function of hydrogen dilution. Silane and germane fluxes are kept constant while hydrogen flow is varying to achieve dilutions up to 80 times. Solid content of principle elements as well as contaminants are determined by SIMS. For low dilutions (from 9 to 30), germanium solid content strongly(More)
Functional properties of rat brain mitochondria were different in Krebs-Ringer solution as compared to these in the media with mannit. Mitochondria in the presence of cytochrme c increased endogenous respiration essentially after the introduction of mannit into the polarographic cell. It is concluded that mannit metabolised by mitochondria as other non-cell(More)
In this work we present a study of material substrates and fabrication process effect on morphological characteristics of Si:H films and related p-i-n structures. Measurements of spectral dependence of optical transmittance of plastic substrates in ultraviolet and visible range were performed. AFM measurements were conducted over area of 10 &#x00D7; 10(More)
In this work we study the influence of hydrogen dilution on morphological properties and electronic of SiGe:H films. Surface morphology measured by Atomic Force Microscopy (AFM) technique and temperature dependence of conductivity, together with conductivity measurements in dark and under AM1.5 illumination at room temperature were used for(More)
Influence of high-sucrose diet and high-sucrose diet supplemented with selenium on proteinase activity in rat small intestinal mucosa and on rats' growth has been examined. Being added to the diet, selenium raised cathepsin D activity and did not change the activity of alkaline proteinase. High-sucrose diet supplemented with selenium led to a two-fold(More)
Temperature dependence of DC conductivity &#x03C3;DC(T) of spin-coated poly (3,4 ethylenedioxythiophene): poly(4-styrenesulfonate) (PEDOT:PSS) films has been studied. &#x03C3;DC(T) was measured in films deposited from mixtures of PEDOT/PSS: H<sub>2</sub>O (1:0.5), PEDOT:PSS (without dilution), PEDOT/PSS: Isopropyl Alcohol (IPA) (1:0.5) and PEDOT/PSS:IPA(More)
Indium tin oxide (ITO) thin films were deposited by magnetron sputtering with different oxygen flows rates (%O<sub>2</sub> = 1 % to 0 %). The films were deposited by RF discharge in argon/oxygen atmosphere with a RF power W = 150 W at substrate temperature T = 175&#x00B0; C and pressure P = 6 mTorrs. Photoelectric parameters of fabricated ITO films were(More)
In this work we study the influence of frontal interface modification with titanium and carbon layers between p<sup>+</sup>-layer and transparent conductive oxide (TCO). Indium titanium oxide (ITO) and zinc oxide doped by aluminum (AZO) are used as TCO. Impact on performance characteristics is determined by current voltage measurements in dark and under(More)
