OverviewAI-generated summary
Yousra Nahas's research focuses on the study of ferroelectric materials, particularly their topological phases and nanostructures. Her work investigates the creation and control of complex polar structures, such as skyrmions, solitons, and bubble domains, within ultrathin films and epitaxial superlattices. She has published research on switchable skyrmion-like polar nanodomains integrated on silicon, topological phases in polar oxide nanostructures, and hexagonal close-packed polar-skyrmion lattices in ultrathin ferroelectric PbTiO3 films.
Her investigations also extend to ferroelectric phase transitions, including frustration near tricritical composition points, and the manipulation of spherical ferroelectric solitons and freestanding ferroelectric bubble domains. Recent work explores the dynamical control of topology in polar skyrmions via twisted light. Nahas collaborates with researchers such as Sergei Prokhorenko and Laurent Bellaiche at the University of Arkansas at Fayetteville, with whom she has published numerous papers. Her scholarship metrics include an h-index of 25, 90 total publications, and 2,589 total citations.
