Evaluating the Local Bandgap Across inxGa1‐xas Multiple Quantum Wells in a Metamorphic Laser via Low‐Loss EELS

Abstract Using high‐resolution scanning transmission electron microscopy and low‐loss electron energy loss spectroscopy, the local bandgap (Eg), indium concentration, and strain distribution across multiple InxGa1‐xAs quantum wells (QWs), on a GaAs substrate, within a metamorphic laser structure are...
