- Time dependence in the synthesis of Cu2FeSnS4 and some of its properties Jorge Humberto Muñoz-Malpica Mery Isabel Espitia-Mayorga María Alejandra Cerón-Achicanoy Jairo Alberto Gómez-Cuaspud Enrique Vera-López Ingeniería Hydrothermal photovoltaic semiconductor Polycrystalline Cu2FeSnS4 materials (abbreviated CFTS) were synthesized by a hydrothermal route implementing a one-step thermal treatment to measure dependence on different reaction times in the stabilization and structural, vibrational, and optoelectronic properties. The structural results have shown a tetragonal system with I-42m spatial group. The vibrational analysis by Raman spectroscopy allowed the identification of additional crystal phases arising from the synthesis procedure and corroborated the presence of a stannite phase. This evaluation showed that the reaction time gave the proposed synthesis procedure, significantly affects the semiconductor behavior of the solids; consequently, the conductivity measurements evidence a decrease from 1.02x106 to 9.84x105 ( at 573 K as the synthesis time increases. These results described above, corroborated that the control of the reaction time provide a tool to successful fine-tune of the structural and conductivity properties of CFTS materials. 2023 artículo científico 0012-7353 https://www.redalyc.org/articulo.oa?id=49677978018 https://www.redalyc.org/journal/496/49677978018/ https://www.redalyc.org/journal/496/49677978018/html/ https://www.redalyc.org/journal/496/49677978018/49677978018.epub https://www.redalyc.org/journal/496/49677978018/movil https://doi.org/10.15446/dyna.v90n225.104457 en http://www.redalyc.org/revista.oa?id=496 Dyna application/pdf Universidad Nacional de Colombia Dyna (Colombia) Num.225 Vol.90
