A comparative study of thermal properties of similar Zn-free and Zn-doped thin films

Zn-doped sprayed thin films have been grown on binary In2S3 substrates under the mean temperature (Td = 320 °C). Further studies Amlouk et al. [M. Amlouk, M.A. Ben Said, N. Kamoun, S. Belgacem, N. Brunet, D. Barjon, Japan Journal of Applied Physics 38 (1999) 26-30]; Lazzez et al. [S. Lazzez, K. Boubaker, M.

In this study, a quantitative comparative evaluation of the thermal properties of the as-grown layers is carried out. The obtained results, parallel to further information, plea for the superior thermal efficiency of the recently proposed Zn-doped ternary compounds.
