The modification in the Cu₂Se thermoelectric system by electron beam irradiation has been carried out in this work. Samples were prepared using the solid-state reaction technique. The prepared samples were irradiated with various energy dosages viz. 50, 100, and 150 kGy. XRD studies reveal that the synthesized samples crystallized in a monoclinic structure. The micro-hardness of the samples decreased with an increase in irradiation dosage. The sample irradiated at 100 kGy dose exhibits the lowest electrical resistivity, moderate Seebeck coefficient, and highest power factor.

高能电子束辐照提高Cu2Se超离子导体的热电功率因数

_{通过电子束辐照对 Cu 2} Se 热电系统进行了改造。使用固态反应技术制备样品。用各种能量剂量照射制备的样品，即。50、100 和 150 kGy。XRD 研究表明合成的样品以单斜晶结构结晶。样品的显微硬度随着辐照剂量的增加而降低。在 100 kGy 剂量下辐照的样品表现出最低的电阻率、适中的塞贝克系数和最高的功率因数。
