Asymmetrical bridgman growth technique for larger and better quality mercury cadmium telluride crystals

Homogenization of zinc distribution in vertical Bridgman grown Cd0.96Zn0.04Te crystals

“…Also it can be seen that (figure 5b) the points of maxima and minima of Zn concentration distribution (which are also the maxima and minima of solid-liquid interface shapes), is shifted away from geometric axis of the grown crystal, showing that the crystal has been grown slightly asymmetric w.r.t. the furnace axis, as has been the present case (Bagai and Borle 1989).…”

“…The Cd 0⋅96 Zn 0⋅04 Te crystals were grown unseeded, in quartz ampoules in vertical Bridgman configuration (Bagai and Borle 1989;Gurumurthy et al 1998). The sample plates were cut from the central part of the crystal, along the growth direction, using an inner diameter annular saw.…”

Improvement in crystalline quality of Cd1−xZnxTe(x=4%) crystals grown in graphite crucible

“…In this paper, we report the growth of Cd 0.96 Zn 0.04 Te crystal ingots (B40 mm diameter, length B10 cm) grown in graphite crucible by modified Bridgman method [18]. These crystal ingots have been characterized to investigate their crystalline quality in terms of dislocation density and high-resolution X-ray diffraction (HRXRD) rocking curve on large area.…”

Effect of hydrogenation on the electrical and optical properties of CdZnTe substrates and HgCdTe epitaxial layers

“…The CZT substrates used in this study were grown by asymmetric vertical Bridgman technique [7]. These undoped wafers were cut from the boules and polished with alumina.…”
