Title (EN) METHOD OF GROWING CRYSTALLINE CADMIUM MERCURY TELLURIDE AND CRYSTALLINE CADMIUM MERCURY TELLURIDE GROWN BY THE METHOD
(FR) PROCEDE DE FORMATION DE TELLURURE DE MERCURE DE CADMIUM CRISTALLIN ET TELLURURE DE MERCURE DE CADMIUM CRISTALLIN FORME A L'AIDE DE CETTE METHODE
Abstract: front page image
(EN)A method of growing crystalline cadmium mercury telluride by a vertical Bridgman process. A problem in growing such crystalline material is to produce significant quantities of material which are both of acceptable crystal quality and are of homogeneous composition. A melt of cadmium mercury telluride (7) is prepared in a sealed ampoule (1), and the crystalline cadmium mercury telluride (11) is grown from the melt (7) by a vertical Bridgman process at a rate of from 0.1 to 2mm per hour. During growth the ampoule (1) is subjected to an accelerated crucible rotation programme which comprises the steps of accelerating the rate of rotation of the ampoule about its longitudinal axis and decelerating the rate of rotation of the ampoule.
(FR)Un procede de formation de tellurure de mercure de cadmium cristallin utilise un procede vertical de Bridgman. Un probleme concernant la formation de ce materiau cristallin consiste a produire des quantites substantielles de materiau ayant a la fois une qualite de cristaux acceptable et une composition homogene. Une masse en fusion de tellurure de mercure de cadmium (7) est preparee dans une ampoule scellee (1), et le tellurure de mercure de cadmium cristallin (11) se developpe a partir de la masse en fusion (7) par un procede vertical de Bridgman a une vitesse comprise entre 0,1 et 2mm/heure environ. Pendant la croissance, l'ampoule (1) est soumise a un programme de rotation acceleree du creuset qui comprend les etapes d'acceleration de la rotation de l'ampoule autour de son axe longitudinal et le ralentissement de la rotation de l'ampoule.
