Dataset contains, comprehensive Molecular-beam epitaxy (MBE) growth parameters i.e. substrate and source temperature of all the sources present in the chamber during growth as well as background pressure and rotation speed. Reflective High-energy electron diffraction (RHEED) videos and Images were recored before, during and after each sample was grown. Additionally, characterization in form of X-ray diffraction (XRD) in there unaltered form are attached.
