Transient Ferromagnetism in Ultrafast Phase Transitions in Perovskites under XUV Irradiation: A Comparative Study of SrTiO3 and KTaO3
Aldo Artimez Pena, Nikita Medvedev
We study ultrafast structural and electronic responses of strontium titanate and potassium tantalate to intense femtosecond irradiation using the XTANT3 multiscale code. It is foun…
Ions leaving no tracks
Azat Abdullaev, Javier Garcia Fernandez, Chloe Nozais +13
The paths of swift heavy ions are typically traceable in solids, because of confined electronic interactions along the paths, inducing what is known in literature as 'ion tracks',…
Ultrafast X-ray interaction with photovoltaic materials: Thermal and nonthermal responses
Aldo ArtÃmez Peña, Nikita Medvedev
Cadmium telluride (CdTe), lead sulfide (PbS), and indium tin oxide (ITO) play crucial roles in various electronic applications where laser treatment enables precise modification of…
Creating mixed-phase states in cadmium sulfide by swift heavy ion irradiation
Aldo ArtÃmez Peña, Nikita Medvedev
CdS has broad applications in solar cells and radiation detectors. We study its response to irradiation with swift heavy ions and determine its damage thresholds. We apply a model…
Effects of non-equilibrium in ultrafast irradiation of matter
Nikita Medvedev
This proceeding discusses nonequilibrium effects in matter exposed to XUV/X-ray irradiation. When ultrashort, intense XUV/X-ray pulses interact with materials, they trigger a compl…
Ultrafast X-ray induced damage and nonthermal melting in cadmium sulfide
Nikita Medvedev, Aldo ArtÃmez Peña
Cadmium sulfide is a valuable material for solar cells, photovoltaic, and radiation detectors. It is thus important to evaluate the material damage mechanisms and damage threshold…
