Abstract:
The growth of single crystals with precisely controlled properties is one of the most demanding goals of modern materials processing, and its realization depends on the application of fundamentals from solid-state physics, chemistry, thermodynamics, and transport phenomena. Bulk semiconductor substrates and many high-power solid-state laser host materials are typically produced by solidification from the melt. The quality of the crystals produced this way hinges on process conditions which are predominantly determined by the transport of heat, mass, and momentum in the melt and crystal. Accura

Single crystals of monoclinic Nd:LaVO4with dimensions up to Ø28 × 21 mm have been grown from the near-stoichiometric melt by the Czochralski method, making use of various seed orientations that are perpendicular to the (010), (10{\overline 1}), (001) and (00{\overline 1}) crystal planes. A sample was also prepared with the seed orientation in an arbitrary direction relative to the crystal. The anisotropic properties of the crystal are manifested in the growth morphology of the as-grown crystals, where different degrees of bulk spiral growth were observed.

Abstract:
The difficulties in growing large-size bulk β-Ga2O3 single crystals with the Czochralski method were numerically analyzed. The flow and temperature fields for crystals that were four and six inches in diameter were studied. When the crystal diameter is large and the crucible space becomes small, the flow field near the crystal edge becomes poorly controlled, which results in an unreasonable temperature field, which makes the interface velocity very sensitive to the phase boundary shape. The effect of seed rotation with increasing crystal diameter was also studied. With the increase in crystal

Abstract:
As a crystal grows, the temperature distribution of the crystal and melt will change. It is necessary to study the dynamic process of single-crystal growth. Due to the relatively low crystallization rates used in the industrial Czochralski growth system, a steady state is used to compute the temperature distribution and melt flow. A two-dimensional axisymmetric model of the whole Czochralski furnace was established. The dynamic growth process of large-size bulk β-Ga2O3 single crystal using the Czochralski method has been numerically analyzed with the parameter sweep method. In this paper, two

The effect of an insulation lid on the growth of 4-inch β-Ga2O3 single crystals by the Czochralski method is analyzed by numerical simulation.

Such benefits make the melt/crystal interface convex, which is conducive to suppressing spiral growth and growing large crystals with high quality.

Abstract:
We will demonstrate that our micro-FT-IR mapping system is highly effective for investigating the behavior of interstitial oxygen (Oi) in Czochralski-grown silicon single crystals. The micro-FT-IR system experiences high space resolution, and Oi striations of as-grown silicon single crystals or of oxygen micro-precipitation after a thermal treatment are quantitatively measured. Oi micro-distribution profiles of as-grown crystals exhibit regular or irregular intervals and height, depending upon their crystal growth conditions. Oxygen micro-precipitations along growth striations are dependent up

Abstract:
We consider the steady-state growth of a single crystal by the liquid encapsulated Czochralski method. The mathematical model accounts for heat transfer in the crystal, melt and encapsulant, radiative heat exchange between the crucible and the surrounding furnace, formation of the growth interface and the melt/encapsulant interface meniscus, release of the latent heat during the phase transition. The time history of the growth is reconstructed from a sequence of steady state calculations with decreasing melt depth. The numerical method is based on explicit interface tracking.

The critical diameter dc = 1.0 cm and the critical rate of rotation ?c = 30 rpm were calculated from hydrodynamic equations for buoyancy-driven and forced convection. The rate of crystal growth was experimentally obtained to be 6.7 mm/h. For chemical polishing, a solution of 1 part saturated chromic acid (CrO3 in water) and 3 parts conc.

A near-stoichiometric lithium niobate single crystal has been grown by the Czochralski method in a hanging double crucible with a continuous powder supply system. Twins were found at one of the three characteristic growth ridges of the as-grown crystal. The twin structure was observed and analyzed by transmission synchrotron topography. The image shifts ΔXand ΔYin the transmission synchrotron topograph were calculated for the 3{\overline 2}{\overline 1}2 and 0\overline 222 reflections based on results from high-resolution X-ray diffractometry.

Abstract:
Indium arsenide (InAs) single crystals heavily doped with Sn are found to have various violations of structural perfection, which depend on the Sn concentration in different regions of crystal. At low charge-carrier (electron) concentrations (~1.5 × 1018 cm–3) an unusual annular distribution of dislocations in the cross section is observed for the initial parts of crystal. The dislocation density lies in the range of (0.1–1.0) × 104 cm–2. At a carrier concentration above 4.0 × 1018 cm–3 indium inclusions and “vicinal growth hillocks” are observed in the final parts of crystals. The dislocation

The purposes of this research were to estimate the crystallite size, density, and chemical composition of the ingot Ti: Al2O3 crystal grown by the Czochralski method. The crystallite size and composition of Ti: Al2O3 crystals had been determined using x-ray diffraction (XRD) and energy-dispersive x-ray spectroscopy (EDXS). Based on the Archimedes principle, the density of the crystals had been determined. The XRD patterns showed a single central peak with high intensity for all samples. It indicated that all samples had a single crystal. The average value of the samples' crystallite size was i
