Growth of lead sulfide single crystals by the bridgman method

Materials Research Bulletin, 1975
Abstract Large crackfree crystals could be grown by the Bridgman technique using graphite ampoules. Their metallurgical properties are typical for Bridgman crystals. However, a high content of carbon is incorporated into the crystals using this method.

Crystal growth of orthorhombic BaSi2 by the vertical Bridgman method

Thin Solid Films, 2004
Melt growth of BaSi2 by the vertical Bridgman (VB) growth method was initiated from barium metal (3 N grade) and semiconductor-grade silicon. Because Ba is highly reactive at the growth temperature (≈1500 K), the crucible materials were chosen to avoid chemical reactions and sticking between the crucibles and the molten and vapor Ba.

Crystal growth from aqueous solution by the Bridgman method

Journal of Physics D: Applied Physics, 1972
The results of attempts to grow crystals from aqueous solutions by the Bridgman technique are described. It is shown that the method is difficult in practice and has no advantage over other methods.

Growth of nickel monosulfide single crystals by the bridgman method

Journal of Crystal Growth, 1976
Abstract Large single crystals of Ni 1-δ S, belonging to the high-temperature NiAs structure, in the range 0⩽ δ ⩽ 0.05 are grown in sealed tubes, by the Bridgman method. Their composition is very uniform as measured by the metal-nonmetal transition temperature and the mosaic spread is less than 30′ in a crystal of 2 cm 3 .

Behavior of antimony in ZnSe grown by a closed Bridgman method

Applied Physics Letters, 2006
High-quality and large-size p-ZnSe single crystals doped with antimony (Sb) have been grown by a Bridgman method using a closed double crucible. Photoluminescence spectra at low temperatures indicate that Sb works as both a shallow acceptor and a deep complex donor.

Modelling of the dynamics of HgCdTe growth by the vertical Bridgman method

Journal of Crystal Growth, 1991
The analysis of Kim and Brown (1989), which described the pseudo-steady state of the HgCdTe melt/crystal system grown by the vertical Bridgman method, is extended to the study of the transients during the crystal growth and, in particular, at the beginning of the growth.

Growth of Bi2Sr2CaCu2Oy Single Crystal by a Vertical Bridgman Method

1998
We prepared Bi2Sr2CaCu2Oy (BSCCO) single crystals by a vertical Bridgman method changing the contents of starting materials, the pulling down rates and the temperatures for melting. From the results, we found that the plate-like BSCCO single crystals with the size of 15 × 7mm2 were obtained and were a (2212) single-phase, when the crystal growth was ...

Crystal Growth of Oxide Superconductors Prepared by the Bridgman Method

1991
The effects of temperature gradient (G) and growth rate (R) on the microstructure and characteristics of Y-based superconductors grown from the partially molten state by the horizontal Bridgman method were studied. The structure showed highly aligned YBa2Cu3Oy crystals containing non-aligned finely dispersed Y2BaCuO5 crystals for high G/R ratio ...
