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

Advanced Materials Interfaces, EarlyView.
This research explores local bandgap, composition, and strain variations across InxGa₁−xAs quantum wells within a metamorphic laser structure using high‐resolution scanning transmission electron microscopy (STEM) and low‐loss electron energy loss spectroscopy (EELS). Results reveal significant inhomogeneities, particularly near interfaces, with bandgap

Self‐Organized Growth of Catalyst‐Free Single Crystal WnO3n‐2 (n = 25) Nanowire Bundles on Si (111) via Selective He+ Ion Irradiation

Advanced Materials Interfaces, EarlyView.
A novel and efficient method is explored to synthesize 1D single‐crystal sub‐stoichiometric WnO3n‐2 (n = 25) nanowire bundles. The approach utilizes selective low‐energy He+ ion irradiation (27 eV) on Mo‐Ni doped WOx surface, achieving efficient catalyst‐free self‐organized growth of high aspect ratio nanowires at the temperature of 700 °C.
