Outline of Final Research Achievements

Mist CVD method is a promising technique for the deposition technology of semiconductors to achieve the use of both solution precursors and vapor phase processes. We demonstrated the deposition of inorganic-organic perovskites in the capor phase via a chemical reaction using the solution precursors. The formation mechanism of the inorganic-organic perovskites grown by the laminar flow-type mist CVD method is a vapor phase reaction in spite of the fact that the solution were used as the CVD precursors. Furthermore, the mist CVD was applied to the growth process for alloying inorganic-organic perovskites taking advantages of using the solution precursors. We have successfully grown the alloying inorganic-organic perovskites (CH3NH3Pb(Br1-xClx)3)by mist CVD.
