Temperature‐Dependent Properties of Atomic Layer Deposition‐Grown TiO2 Thin Films

open access: yesAdvanced Materials Interfaces, EarlyView.
This study explores the temperature‐dependent properties of TiO₂ thin films grown by atomic layer deposition using tetrakis dimethyl amino titanium and water. The films exhibit increased oxynitride incorporation as the process temperature increases from 150 to 350 °C, significantly influencing their optical and electrical properties. Findings highlight

High‐Resolution and Surface‐Sensitive Tip‐Enhanced Raman Spectroscopy Characterization of Strained‐Silicon Devices through Cleanroom‐Compatible Plasmonic Probes

open access: yesAdvanced Materials Interfaces, EarlyView.
This paper demonstrates how Tip‐Enhanced Raman Spectroscopy (TERS) can detect diverse levels of strain in a SiGe‐Si structure in less than 20 nm of depth with lateral resolution under 100 nm. The measures are performed with a TiN‐coated probe, which secures a remarkable enhancement of the optical signal, while being chemically stable to allow TERS to ...

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.

Advancement in Colloidal Metasurfaces: Approaches for Scalable Photonic Devices

open access: yesAdvanced Materials Interfaces, EarlyView.
This perspective explores colloidal metasurfaces composed of plasmonic and emitting nanoparticles assembled by laser interference lithography and template‐assisted self‐assembly methods. Precise design strategies achieve directional emission, low‐threshold lasing, and tunable photonic bandgaps.
