Lattice Dynamics of Rutile Germanium Dioxide (r‐GeO2)
The rutile polymorph of GeO2 is a promising ultra‐wide bandgap material, but key properties for its technological exploitation remain poorly understood. Using polarization angle‐resolved Raman spectroscopy, we resolve long‐standing uncertainties in the energies of Raman‐active phonons and extract relative Raman tensor elements.

Robust C–V Ratio Technique for Profiling Defects in Proton‐Irradiated 4H‐SiC
A noise‐robust C–V ratio technique is introduced to profile radiation‐induced defects in proton‐irradiated 4H‐SiC Schottky diodes. By using analytical capacitance ratios instead of numerical differentiation, the method directly extracts trap‐density and effective trap‐energy profiles at room temperature.

Heterogeneous Integration of Flipped Oxide Heterostructure Membranes for Nanoelectronics
A flipped electronically reconfigurable STO/LAO freestanding membrane is demonstrated and integrated with various host platforms via controlled transfer. Using ultra‐low‐voltage electron‐beam lithography, conductive nanostructures are created at the buried STO/LAO interface. This novel approach enables heterogeneous integration of flipped complex oxide

Pressure‐Induced Structural and Magnetic Evolution in Layered Antiferromagnet YbMn2Sb2
Pressure tunes the delicate balance between structure, magnetism, and electronic states in quantum materials. In YbMn2Sb2, high‐pressure X‐ray and neutron diffraction reveal a trigonal‐to‐monoclinic transition near 3.5 GPa, accompanied by unconventional magnetic ordering.

Halide segregation (HS) in mixed‐halide wide‐bandgap (WBG) perovskites is key to the stability of perovskite‐based tandem cells and a central focus of large‐scale research efforts. Here, we find that the underlying reason for the poor stability of cells prone to HS is enhanced ionic losses during operation. Furthermore, we identified irreversible ionic
