“…However, the numerical simulated gradient temperatures are higher than the experimental ones. This difference may be due to the temperature profile assumed for the radiative element [13]. In addition, there is a lower deviation of the experimental results from the theoretical ones for the C configuration.…”

“…The experimental measurement agrees with the theoretical prediction, and the lower gradient temperature was obtained in the experience C. But in the case of the numerical simulation the gradient temperature are higher than the experimental values. We think that this difference should be due to the temperature profile assumed for the radiative element [13]. In addition, the deviation of the experimental results compared than the theoretical are lower in the experience C. This fact should be explained if we consider that the inclusion of the alumina insulating element is a buffer between the radiative element and the growth chamber [13].…”

“…In addition, there is a lower deviation of the experimental results from the theoretical ones for the C configuration. This fact may be explained considering that the alumina insulating element acts as a buffer between the radiative element and the growth chamber [13]. Other important points are that the feed zone practically is not affected for the change in the configuration of the insulating material, and that the effect of this element on the radial temperature gradient is practically negligible.…”

“…For this purpose, we established the following assumptions: stationary system, wall to wall radiation, heat transfer mechanisms inside the growth chamber are radiation and conduction (neglecting the convection mechanism) and mass transfer phenomena were not considered. Details about the numerical model are reported elsewhere [13].…”

CdTe single crystal, were grown by the Modified Markov Method. We have introduced an insulating element between the furnace and the growth chamber, trying to minimize the radiation effects in the crystal. Numerical simulation of the heat transfer phenomena predict a reduction of the axial temperature gradient in the growth chamber, confirming by numerical experimental measurements, leading to a more uniform growth. An improvement in the surface morphology and in the crystal quality as well was achieved, evaluated by the combination of X-ray rocking curves, etch pit density determination and low temperature photoluminescence.
