(1) LEDs: made brighter/ more efficient by connecting crystal structure directly to both efficiency/ advanced optical functionality minimizing energy dissipation from iodine vacancies, (2) solar cells: improve stability/ power conversion efficiency by minimizing energy dissipation from iodine vacancies (3) spintronics/ quantum devices: benefited by resulting Rashba effect, exhibiting 2 subbands with opposite spin states... also benefited by resulting circularly polarized light emission... (4) secure optical communication: also benefited"
