Simple route to β-Ga2O3/air-gap structures:
This study demonstrates the fabrication of β-Ga2O3/air-gap structures on (001) substrates via crystallographic HCl-gas etching. At 650 °C, vertical and lateral etch rates of 0.10 μm/min and 0.70 μm/min along deliver strong orthogonal anisotropy, enabling cantilevers and air bridges without wafer bonding or transfer steps. This straightforward, substrate-compatible approach paves the way for integrating β-Ga2O3-based MEMS and power electronic devices.

Emergent ferromagnetism at 2D-MXene interfaces
This study probes the origin of ferromagnetism on 2D-MXene surfaces using XMCD and angle-dependent HAXPES. High-quality Cr2N/Co, Cr2N/Pt, and Cr2N/Cu bilayers were prepared to disentangle charge transfer from interlayer exchange coupling. Results show that only Cr2N/Co exhibits an induced Cr magnetic moment at room temperature, and HAXPES confirms interlayer exchange coupling—not charge transfer—as the driving mechanism. These findings advance our understanding of interface magnetism in MXene-based heterostructures.

Controlled HCl-gas etching of β-Ga2O3 for device applications
This study investigates planar and lateral etching of (001) β-Ga2O3 in HCl gas under oxygen supply. Findings show that even minimal O2 reduces surface roughness below 2 nm, while temperature strongly influences lateral anisotropy and facet formation. Results highlight the potential of plasma-free etching to achieve smooth surfaces and tailored morphologies for high-performance β-Ga2O3 devices.

Mapping residual stress in diamond films with quantum sensors:
Using NV centers, this study visualizes the residual stress tensor in nitrogen-doped CVD diamond (001) films. Shear and compressive stress components were identified, along with a ~0.073% lattice contraction linked to nitrogen concentration differences. These insights pave the way for stress-engineered diamond quantum devices.
