Influence of ionization and cumulative effects on laser-induced crystallization in multilayer dielectrics
Crystallization of amorphous layers has been demonstrated under various radically different laser-exposure conditions, including continuous wave (cw) and pulsed lasers. Here, we investigate the specific role of ionization in the crystallization of dielectr ...
2024Femtosecond-laser direct-write photoconductive patterns on tellurite glass
Yves Bellouard, Gözden Torun, Anastasia Romashkina
We report the formation of arbitrary photoconductive patterns made of tellurium (Te) nanocrystals by exposing a tellurite (TeO2-based) glass to femtosecond laser pulses. During this process, Te/TeO2-glass nanocomposite interfaces with photoconductive prope ...
2024Shaped Laser Pulses for Microsecond Time-Resolved Cryo-EM: Outrunning Crystallization during Flash Melting
Marcel Drabbels, Constantin Richard Krüger, Nathan Junior Mowry
Water vitrifies if cooled at rates above 3 × 105 K/s. In contrast, when the resulting amorphous ice is flash heated, crystallization occurs even at a more than 10 times higher heating rate, as we have recently shown. This may present an issue for microseco ...
2024Disclination states in nonreciprocal topological networks
Romain Christophe Rémy Fleury, Haoye Qin, Qiaolu Chen, Zhechen Zhang
Recently, nonreciprocal two-dimensional unitary scattering networks have gained considerable interest due to the possibility of obtaining robust edge wave propagation in their anomalous topological insulating phase. However, zero-dimensional states in such ...
