Microsphere Autolithography—A Scalable Approach for Arbitrary Patterning of Dielectric Spheres
Advanced Functional Materials, EarlyView.MicroSphere Autolithography (µSAL) enables scalable fabrication of patchy particles with customizable surface motifs. Focusing light through dielectric microspheres creates well defined, tunable patches via a conformal poly(dopamine) photoresist. Nearly arbitrary surface patterns can be achieved, with the resolution set by the index contrast between ...

Quantifying Spin Defect Density in hBN via Raman and Photoluminescence Analysis
Advanced Functional Materials, EarlyView.An all‐optical method is presented for quantifying the density of boron vacancy spin defects in hexagonal boron nitride (hBN). By correlating Raman and photoluminescence signals with irradiation fluence, defect‐induced Raman modes are identified and established an relationship linking optical signatures to absolute defect densities. This enables direct

Self‐Trapped Hole Migration and Defect‐Mediated Thermal Quenching of Luminescence in α‐ and β‐Ga2O3
Advanced Functional Materials, EarlyView.Temperature‐dependent photoluminescence and first‐principles calculations reveal self‐trapped hole migration as the microscopic origin of thermal quenching in α‐ and β‐Ga2O3. The low migration barrier in α‐Ga2O3 enables defect trapping and enhances blue luminescence, while the higher barrier in β‐Ga2O3 preserves ultraviolet emission at elevated ...
