The possibility of semiconducting BaSi2 films for potential application in thin-film solar cells has already been explored by several research groups. Literature review reveals that to grow thin-films of BaSi2, techniques including molecular beam epitaxy (MBE), vacuum evaporation, solid phase epitaxy (SPE), RF magnetron sputtering, etc., have been reported by this time.
Is it possible to fabricate a BaSi2 film on the SLG substrate using chemical deposition process, in particular, using the sol-gel spin-coating method?
Thanks in advance.
Dear M. Ajmal Khan Sir,
I would be highly obliged if you could please put some light on this issue: Is there any chance to fabricate BaSi2 film using the sol-gel spin coating method?
Thanks in advance.
Regards,
MMA Moon

Dear Md. Mahabub Alam Moon thank you for asking this very interesting technical question. To the best of my knowledge, sol-gel methods cannot be applied to deposit BaSi2 (barium silicide) because this material is moisture sensitive. Thus it cannot be synthesized using solution-based techniques. According to the relevant article cited below, BaSi2 films have previously been grown using molecular beam epitaxy (MBE) and radio-frequency sputtering methods. In addition, the authors of this article report a "simple" vacuum evaporation technique to produce BaSi2 thin films for solar cell applications. Please see for yourself if this can be reproduced in your lab:

Dear Professor Frank T. Edelmann,
Thank you so much for responding to my question. Highly obliged...
