Abstract
In this work, in situ cathodoluminescence (CL) is presented as a techn ique to optimize the molecular beam epitaxy (MBE) growth conditions fo r InGaN films and structures. InGaN was grown at 1 mu m/h using a reac tive nitrogen rf plasma source at substrate temperatures ranging from 550 to 650 degrees C. The quick determination of the emission waveleng th and quality from the peak position and width allowed various growth conditions and structures to be tried without removal of the sample f rom the MBE system. CL scans are presented from samples grown under va rying Ga/In flux ratios, III/nitrogen flux ratios, and substrate tempe ratures showing the usefulness of in situ monitoring for MBE InGaN gro wth.
