DEWETTING AND STRUCTURAL QUALITY OF CdTe:Zn:V GROWN IN SPACE

Dewetted growth and characterisation of high-resistivity CdTe

“…Nevertheless, the yield is still limited by the inherent contact between the crucible and the crystal which causes stresses in material. The absence of this contact was observed only in the microgravity experiments due to the dewetting phenomenon, and crystals grown under these conditions demonstrated an improved quality [18][19][20].…”

Dewetting application to CdTe single crystal growth on earth

“…Indeed, CdTe crystal growth experiments under microgravity conditions have shown such an improvement in the presence of dewetting [4,5]. The present paper deals with the ground-based application of the dewetting process to the growth of CdTe single crystals.…”

Contribution to the stability analysis of the dewetted Bridgman growth under microgravity conditions

“…However a number of experiments under microgravity conditions have been performed with an open crucible, which means that there was no pressure difference in the system. This point has been more precisely studied in a dedicated CdTe microgravity growth experiment, comparing the results obtained with a close and an open crucible, and the dewetting has been the same in both configurations [18,19]. This experiment also showed that dewetting is not dependant on the growth rate, meaning that mechanism 4) was not the most relevant.…”
