Optical spectroscopies cannot differentiate between bulk and surface traps in contrast to spin-resonance techniques, which in principle avail chemical information on such trap sites. Magnetic resonance detection via spin-controlled photoluminescence enables the direct observation of interactions between emissive excitons and trapped charges. This approach allows the discrimination of two functionally different trap state","authors_text":"Christoph Boehme, Dmitri V. Talapin, Jing Huang, John M. Lupton, Kipp J. van Schooten, William J.
