摘要:
AbstractThe thermal conditions at the liquid/solid interface are characterized by temperature measurements in the melt and on the growing crystal with 〈001〉‐seed orientation. The thermal boundary layer was determined, from which the relation of effective thermal conductivity of the liquid and solid phase was found to be λl,eff/λs,eff= 0.25. The liquid/solid interface is extremly convex towards the melt and has a conical shape. When the crystal diameter reaches a certain value the cone was truncated with the formation of a facet in the centre. This typical interface shape is mainly the result of a difference between the effective thermal conductivity of melt and

摘要:
AbstractSome gas phase processes during the vacuum vertical directed crystallization of α‐Al218O3are studied in this paper. An effect of these processes on the H, C, N concentrations in the crystals is discussed. The detected pulsations of partial H2and C18O pressures are a result of bubble destruction at the melt‐gas interface. The C18O bubbles are formed because of chemical interaction between the melt and carbon‐containing phases of container material. Besides the container wall, the H2bubbles can be generated also at the crystallization front supersaturated by H2. The perfect α‐Al2O3and α‐Al218O3crystals grown under the same conditions have noticeable differences of their density, microhardness and lattice parameters. This is explained by an isotopic substit

摘要:
AbstractFollowing the Charnell's procedure, the influence of materials, methods of preparation and changes in composition of the gel on the process of NaX zeolite crystallization have been investigated in order to find conditions providing both the growth of crystals as large as possible and also good reproducibility of the result. The experimental conditions used are detailed described.

摘要:
AbstractA series of epitaxial layers of the InGaAs alloy were deposited on (001) oriented InP substrates by using hydride VPE technique. The layers were characterized by Double Crystal Diffractometry (DCD), Photoluminescence (PL), Hall effect and Capacitance‐Voltage (C‐V) measurements. The growth parameters and the quality of the grown layers are discussed on the basis of electrical and structural data analy
