To obtain short period superlattices (SPLS) of In_xGa_1−xN/GaN in most cases molecular beam epitaxy has been applied. In this work the metal‐organic vapor phase epitaxy was used for obtaining similar structures and their quality as well as light emission features are studied. Thanks to control of growth parameters it was possible to fabricate In_xGa_1−xN/GaN SPSLs with structural quality of structures grown by MBE. They contain around 30% of indium in quantum wells (QWs) and different number m of atomic monolayers in QWs, and n. in the barriers. X‐ray diffraction and transmission electron microscope measurements have confirmed that the designed SPSLs structures were obtained. An agreement between the experimental results of photoluminescence measurements and theoretically predicted band gap behavior of SPSLs composed of mIn_xGa_1−xN/nGaN was achieved. Built‐in electric field in quantum wells and barriers of the selected structures were determined using a simplified method of calculation.
