Implication

Time-resolved phase microscopy examines charge carriers in Al-doped SrTiO₃, suggesting insights into photocatalytic performance.

Abstract

Al-doped SrTiO₃ (SrTiO₃:Al) exhibits exceptional performance for photocatalytic overall water splitting, yet the microscopic origins of its long-lived charge carriers remain insufficiently understood. Patterned-illumination time-resolved phase microscopy (PI-PM) was applied...
