Modeling the vertical Bridgman growth of cadmium zinc telluride II. Transient analysis of zinc segregation

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. Among those alloys, the pseudo-binary semiconductor GaSb-InSb is an important material for optoelectronic applications as photodetectors and thermophotovoltaic cells.…”

Analysis of the growth of cadmium zinc telluride in an electrodynamic gradient freeze furnace via a self-consistent, multi-scale numerical model

“…Sen et al [20], Pfeiffer and Mu¨hlberg [21], and Parfeniuk et al [22], employed models that neglected melt convection, which is important in this system. Since then more detailed two-dimensional models have been developed to study the application of both vertical [23][24][25][26] and horizontal [27][28][29] Bridgman methods to the production of CZT substrates. Ghaddar et al [30] used a three-dimensional model to study the effect of rotating magnetic field to suppress buoyant melt convection in CdTe grown in by traveling heater method in a micro-gravity environment.…”

Three-dimensional imperfections in a model vertical Bridgman growth system for cadmium zinc telluride

“…The g-ray devices promise to be very useful in portable, sensitive detectors for medical imaging and monitoring of nuclear material [22][23][24]. This material is also extremely difficult to grow [25][26][27] and has been the object of numerous studies, including a notable microgravity experiment by Larson et al [28,29] on USML-1 and USML-2 and extensive modeling by Derby and co-workers [14,[30][31][32][33][34][35][36][37][38][39]. Cadmium telluride and its alloys have unusual thermophysical properties which make their growth very different from other semiconductor crystals.…”
