Low-temperature photoluminescence and X-ray photoelectron spectroscopy prove the n + shell significantly suppresses the surface-related recombination by spatially modulating the electronic band structure. The study provides a significant physical insight in designing optoelectronic devices.EnglishBand engineeringCore - shell structuresGallium dopingNanorodsSurface depletionZnOArticle10.1002/adom.201500087
