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

open access: yesAdvanced 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

open access: yesAdvanced 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.

Scaled‐Up Graphene Growth Through Chemical Vapor Deposition Over Large‐Area Liquid Cu Catalysts

open access: yesAdvanced Materials Interfaces, EarlyView.
Scaling up the catalyst area fivefold and improving molten catalyst cleaning minimize reactor kinetic effects, enabling reaction kinetics to dominate graphene growth. This results in high‐quality graphene with controlled layering and measurable nucleation rates.

Ultra‐Flexible µ‐ECoG Arrays Based on PEDOT:PSS Micropillars

open access: yesAdvanced Materials Interfaces, EarlyView.
This work demonstrates an efficient procedure for fabricating ultra‐flexible neural interfaces endowed with micropatterned microelectrodes to increase surface area and characterized by extremely low impedance values to enable high‐quality recordings. The home‐built device has been shown to record somatosensory evoked potentials in vivo with exceptional
