Photo-induced stabilization and enhancement of the ferroelectric polarization in BaSrTiO/LaCa(Sr)MnO thin film heterostructures
Y. M. Sheu, S. A. Trugman, L. Yan +5
An emerging area in condensed matter physics is the use of multilayered heterostructures to enhance ferroelectricity in complex oxides. Here, we demonstrate that optically pumping…

Free-carrier relaxation and lattice heating in photoexcited bismuth thin films
Y. M. Sheu, Y. J. Chien, C. Uher +2
We report ultrafast surface pump and interface probe experiments on photoexcited carrier transport across single crystal bismuth films on sapphire. The film thickness is sufficient…

Ultrafast carrier dynamics and radiative recombination in multiferroic BiFeO
Y. M. Sheu, S. A. Trugman, Y. -S. Park +6
We report a comprehensive study of ultrafast carrier dynamics in single crystals of multiferroic BiFeO. Using femtosecond optical pump-probe spectroscopy, we find that the ph…
