Furthermore\, photonic sin tering studies are introduced\, illustrating fast and energy-efficient densification of functional ceramics. Dislocations generate local str ain fields and space charge regions that modify defect equilibria\, th ereby enabling dislocation-mediated enhancement of electronic and ioni c transport in oxides such as TiO₂ and yttria-stabilized zirconia\, as well as strongly increased photoconductivity in SrTiO₃. Controlle d plastic deformation produces well-defined dislocation arrays\, and t heir mesoscale arrangement governs macroscopic conductivity. With the help of local microelectrode and tracer experiments\, we can quantify dislocation-enhanced charge and mass transport. Building on these insi ghts\, we can demonstrate that dislocation-rich oxides serve as effici ent photocatalysts for reactions such as heterogeneous H₂O₂ synthe sis and that mechanical tailoring of dislocation density opens a desig n space for catalytic and optoelectronic functionality. Finally\, the talk will introduce photonic sintering of ceramics\, where intense blu e/UV illumination\, assisted by temperature-dependent absorption and e missivity\, enables rapid densification of a range of functional ceram ics within seconds. This approach offers new opportunities for fast\, energy-efficient processing of solid electrolytes and dielectric or se miconductor oxides and points toward advanced light-driven sintering i n ceramic device manufacturing.
