Bismuth subnitrate is a basic salt of bismuth, i.e. a mixed nitrate-hydroxide salt. It's insoluble in water but soluble in HCl and in HNO3. If you can use a strongly acidic solution as a starting point for your semiconductor then - yes.

Guohua zhang Zhang

yes, I think so.

Maybe you can get a superconductor which maybe have the 130K critical temoerature (highest in theory)
