Crystal structure and transmission of Q2 JNSN4 nanoparticles, electron microscopy and electron defraction.
Detailed analysis of the structure of Q2JNSN4 (CJETS) nanocrystals is synthesized with hot-injection in the presence of oilymline, high resolution temple, selected area electron diffraction (SAED) and convergence beam electron diffraction (CBED) is provided. . The nanostructure was examined after the vacuum thermal treatment at 550 ° C. Grown material contains polycrystalline particles with an average size of 7 ± 3 nm, which increase on average 53 ± 13 nm after the vacuum annealing phase. This thermal treatment can investigate the early stages of high quality film development in photovoltaic devices. Group of SAED and CBED patterns, where different crystal different key axes were observed after the annealing, which enabled us to reveal the presence of weak reflections due to the cation order and confirm a testosterone unit cell Which is either Castorate or Stannate structure
