Direct Observation of Dry Etch‐Induced Selectivity Tailoring of Alkylate Inhibition Layer Using DMATMS Vapor

open access: yesAdvanced Materials Interfaces, EarlyView.
This study demonstrates that tailoring surface ─OH groups on SiO2 and SiNx via dry etching significantly enhances the selectivity of DMATMS adsorption, achieving a 92.2% selectivity in subsequent Ru layer growth. In situ spectroscopy reveals that removal of ─OH groups reduce DMATMS reactivity on SiNx but not on SiO2, providing insights for improving ...

Pump‐Probe Imaging of Ultrafast Laser Percussion Drilling of Glass in Single Pulse, MHz‐ and GHz‐Burst Regimes

open access: yesAdvanced Materials Interfaces, EarlyView.
Pump‐probe shadowgraphy of glass drilling is shown with a femtosecond laser operating in MHz‐ and GHz‐burst regime. A comparison with standard femtosecond micro‐processing using repetitive single pulses is provided. The ablation plume lifetime is measured in all three regimes, and the drilling dynamics of Through Glass Via (TGV) in GHz‐burst mode are ...

Defect Generation and Evolution in Irradiated Epitaxial Films and Heterostructures of Fe3O4 and Cr2O3

open access: yesAdvanced Materials Interfaces, EarlyView.
The functionality of nuclear structural materials, sensors, and microelectronics in radiation environments relies on understanding defect generation and evolution processes in oxide layers. The initial radiation response of Fe3O4 epitaxial thin films is characterized by the formation of large vacancy clusters, but these defects do not lead to lattice ...

Borophene‐Based Ultrasensitive and Broadband Photodetectors

open access: yesAdvanced Materials Interfaces, EarlyView.
The direct growth of χ3‐phase borophene on n‐type silicon wafers leads to superior Schottky junctions, making them ideal for broad‐range, high‐sensitivity photodetectors. These photodetectors demonstrate higher sensitivity and faster response times compared to those fabricated by transferring 2D materials onto silicon to form van der Waals junctions ...

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.

Texture‐Enhanced Mechanical Stability of Transparent Electrodes for Flexible Optoelectronics with Near‐Infrared Response

open access: yesAdvanced Materials Interfaces, EarlyView.
Texturing of indium tin oxide (ITO) electrodes on plastic substrates is found to enable both, a remarkable transparency up to the near‐infrared region, and a massively enhanced mechanical stability upon bending. Therefore, textured ITO electrodes are an appealing option for flexible opto‐electronic applications with near‐infrared response, such as all ...
