Self-diffusion in liquid tellurium and liquid te_99%-se_1%

Abstract

Abstract Self-diffusion coefficients of Te and Se in pure Te or in SeX-Te1-x (x = 0,01) alloy, have been measured by using the capillary-reservoir technique. The results are presented by an Arrhenius law, D = 1,02.106 exp/ (-35.500/RT) for DTe Te∗ and D = 0,41 exp (-9.200/RT) for DDe x Se∗-Te 1-x(x = 0,01). Results are analysed and compared to solid Telurium self-diffusion data, Einstein - Stokes- Eyring equation and March-Brown's approximation.
