Growth and characterization of Hg1−xCdxSe alloys

Experimental study of the solid–liquid interface dynamics and chemical segregation in concentrated semiconductor alloy Bridgman growth

“…It was shown that the resulting chemical field in the grown sample is an intricate interaction of convection in the melt, heat and solutal transfers, and variation of the interface temperature with the chemical composition. However, these theoretical and numerical developments have never been validated by comparison with experimental data which generally focus only on the axial segregation, seldom on comprehensive radial segregation analysis [7,29]. Only few attempts were made to measure the interface velocity or shape [3,[30][31][32], always by quenching the remaining liquid.…”

“…This leads to strong axial and radial chemical segregations, with large lattice parameter variations and associated mechanical stresses, so that the samples are generally heterogeneous and cracked. However, some other times, the crystals were found unexpectedly homogeneous [6,7]. In order to avoid axial segregation, a number of technical variants were developed [8][9][10][11][12][13][14][15][16][17][18].…”

Numerical analysis of solute distribution and interface stabilization during experimental Bridgman growth of concentrated GaInSb alloys

“…[1][2][3]. The experimental work has been coupled with numerical [4][5][6][7] and theoretical [8,9] analysis in order to understand the physical phenomena involved in the directional solidification of these alloys.…”

A Study on Radial and Axial Temperature Effects on the Growth of Bulk Single Crystal of SixGe1-x in Bridgman Setting

“…This leads to strong axial and radial chemical segregations, with large lattice parameter variations and associated with mechanical stress, so that the sample are generally heterogeneous and cracked. However, some other times as shown by Andrews et al [71] and Cobb et al [72], the crystals were found unexpectedly homogeneous. It should be noted here that several technical methods and attempts have been developed, such as micro-gravity condition and application of magnetic field to deal with aforementioned problems.…”
