Precipitates in PbTe:Cr crystal grown by the Bridgman method
Journal of Crystal Growth, 1987X-ray diffraction measurements and electron microprobe analysis were performed on the PbTe crystals grown by the Bridgman method doped with 1.2 wt% Cr. The scanning electron microscopic observations and electron microprobe analysis carried out on the (110) oriented samples revealed needle-like precipitates enriched in chromium and tellurium.

Behaviour of Mn in GaSb grown by the Bridgman method
Materials Science and Engineering: B, 1994Abstract Mn-doped gallium antimonide crystals were grown by the vertical Bridgman method. The surface morphology was studied with the high resolution microscope and the etch pit density (EPD) was determined by the image analysis method. The absolute distribution coefficient k absolute and the active distribution coefficient k ...

Crystal growth of PbFCl by modified Bridgman method
Journal of Crystal Growth, 2003Abstract Lead fluoride chloride (PbFCl) crystal was grown by modified Bridgman method. The result of X-ray powder diffraction pattern (XRD) was well accordant with the data of JCPDS card. The transmittance spectrum was first reported without absorption band from 270 to 800 nm.

Bi12SiO20 single crystal growth by the Bridgman method
Journal of Crystal Growth, 1993Abstract The Bridgman growth of bismuth silicon oxide (BSO) crystals along 〈001〉, 〈110〉, 〈111〉 and 〈112〉 directions is reported in this paper for the first time. The mechanism of the darkened core formation in the Bridgman grown BSO crystals has been clarified on the basis of the investigation of the Czochralski growth of BSO.

Growth of large CdTe crystals by the Bridgman method
Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 1992Abstract Large (diameter > 50 mm and length > 120 mm) CdTe crystals have been grown by the vertical Bridgman method. The crystal growth processes have been carried out under the following conditions: the growth rate was changed in the interval 1.0–2.2 mm/h and the crystals were doped with CdCl 2 (about 200 ppm) or Cdl 2 (about 300 ppm).

Growth and characterization of KNbO3 by vertical Bridgman method
Journal of Crystal Growth, 2003Abstract Potassium niobate (KNbO 3 ; KN) was grown from a K 2 O-Nb 2 O 5 flux using the vertical Bridgman (VB) method. By optimizing a flux composition, soaking temperature, the pulling down rate of crucible, and temperature gradient, we were able to successfully grow a pale white and partially colorless KN crystal, 10 mm in diameter and 50 mm in ...

Simulation of Industrial Crystal Growth by the Vertical Bridgman Method
2003Single crystals of Cadmium-Zinc-Telluride are used as a substrate material for the production of infrared detectors and are usually grown by the vertical Bridgman method. We present a simulation of the whole growth process in two steps: In the first step, the (stationary) heat transport in the furnace is modeled and calculated for different positions ...

High yield, single crystal ice via the Bridgman method
Review of Scientific Instruments, 2016The surface chemistry of ice and of water is an important topic of study, especially given the role of ice and water in shaping the environment. Although snow, granular, and polycrystalline ice are often used in research, there are applications where large surface areas of a known crystallographic plane are required.

Growth by Bridgman method and luminescence properties of Na:PbFCl crystal
Journal of Crystal Growth, 2004Lead fluoride chloride crystal with doped sodium was grown by modified Bridgman method. Crystal growth and luminescence properties including transmittance, photoluminescence, X-ray excited luminescence and luminescence decay time are discussed. Photoluminescence measure shows that the luminescence intensity of crystal is improved by doped sodium.
