Tellurium-selenium-cadmium target material, tellurium-selenium-cadmium powder and preparation method thereof
The invention belongs to the technical field of target material preparation, and discloses a tellurium selenium cadmium target material preparation method, which comprises: mixing cadmium selenide and cadmium telluride according to a molar ratio of 5-7: 3 to prepare powder, carrying out die filling, pre-pressing and vacuum pressing on the powder to obtain a biscuit, and finally carrying out vacuum sintering and cooling on the biscuit to obtain the tellurium selenium cadmium target material. According to the method, the relative addition amount of cadmium selenide in the raw materials is increased, so that the prepared tellurium-selenium-cadmium target material is rich in free substances, due to the existence of the free substances, the tellurium-selenium-cadmium target material obtains the carrier lifetime longer than that of cadmium telluride, meanwhile, selenium also has the effect of passivating defects in tellurium-selenium-cadmium, and the tellurium-selenium-cadmium target material can be used for preparing the tellurium-selenium-cadmium target material. Therefore, the number of defects in the tellurium-selenium-cadmium target material is reduced, the relative density of the target material is improved to a certain extent, and in addition, the invention further discloses the tellurium-selenium-cadmium target material, tellurium-selenium-cadmium powder and a preparation method of the tellurium-selenium-cadmium target material.
本申请属于靶材制备技术领域，公开了一种碲硒镉靶材的制备方法，该方法先将硒化镉、碲化镉按5～7：3的摩尔比混合，制得粉体，再将粉体装模、预压、真空压结，得到素坯，最后将素坯真空烧结、冷却，得到碲硒镉靶材，上述方法通过提升原料中硒化镉的相对添加量，使制得的碲硒镉靶材中富含游离物，而因为上述游离物的存在，使得碲硒镉靶材获得比碲化镉更高的载流子寿命，同时再加上硒还具有钝化碲硒镉中的缺陷的作用，进而降低了碲硒镉靶材内部的缺陷数量，并且在一定程度上提升了靶材的相对密度，此外，本申请还公开了一种碲硒镉靶材、碲硒镉粉末及其制备方法。
