Abstract
Przedmiotem wynalazku jest sposób wytwarzania kryształów na bazie CdTe o dużej średnicy, to znaczy o średnicy równej 3 całe lub większej i o wadze ponad 2,5 kg metodą Bridgman'a. Według sposobu, dobrze wymieszane, pierwiastki materiału wsadowego (Cd, Zn i Mg, Te, Mn) materiału wsadowego umieszcza się w ampule kwarcowej znajdującej się w poziomym piecu i prowadzi się proces termiczny. W pierwszej fazie procesu, do temperatury 350 – 380°C wzrost temperatury prowadzi się z szybkością 70 - 90°C/h, następnie zwalnia się szybkość grzania do 2 – 3°C/h. Po osiągnięciu przez ampułę temperatury 430 – 450°C, zatrzymuje się grzanie i temperaturę utrzymuje na tym poziomie przez co najmniej kilka godzin. Po tym czasie podnosi się temperaturę z szybkością ~10°C/h do temperatury 1090 - 1100°C, pionizuje się piec i prowadzi się w znany sposób dalszy proces krystalizacji.The present invention relates to a method for producing large diameter CdTe-based crystals, i.e. 3 or more in diameter and weighing more than 2.5 kg, by the Bridgman method. According to the method, the well mixed elements of the charge material (Cd, Zn and Mg, Te, Mn) of the charge material are placed in a quartz ampoule located in a horizontal furnace and the thermal process is carried out. In the first phase of the process, to the temperature of 350-380 ° C, the temperature is increased at the rate of 70-90 ° C / h, then the heating rate is slowed down to 2-3 ° C / h. After the ampoule has reached a temperature of 430-450 ° C, heating is stopped and the temperature is kept at this level for at least several hours. After this time, the temperature is increased at a rate of ~ 10 ° C / h to a temperature of 1090 - 1100 ° C, the furnace is verticalized and the further crystallization process is carried out in a known manner.
