Non-equilibrium pathways to emergent polar supertextures
Vladimir A. Stoica, Tiannan Yang, Sujit Das +31
Ultrafast stimuli can stabilize metastable states of matter inaccessible by equilibrium means. Establishing the spatiotemporal link between ultrafast excitation and metastability i…
Single laser pulse driven thermal limit of the quasi-two dimensional magnetic ordering in SrIrO
Ruitang Wang, J. Sun, D. Meyers +10
Upon femtosecond-laser stimulation, generally materials are expected to recover back to their thermal-equilibrium conditions, with only a few exceptions reported. Here we demonstra…
Persistent Ionic Photo-responses and Frank-Condon Mechanism in Proton-transfer Ferroelectrics
Xuanyuan Jiang, Xiao Wang, Pratyush Buragohain +8
Photoexcitation is well-known to trigger electronic metastable states and lead to phenomena like long-lived photoluminescence and photoconductivity. In contrast, persistent photo-r…
Ultrafast carrier-lattice interactions and interlayer modulations of Bi2Se3 by X-ray free electron laser diffraction
Sungwon Kim, Youngsam Kim, Jaeseung Kim +20
As a 3D topological insulator, bismuth selenide (Bi2Se3) has potential applications for electrically and optically controllable magnetic and optoelectronic devices. How the carrier…
Dynamic Tilting of Ferroelectric Domain Walls via Optically Induced Electronic Screening
Youngjun Ahn, Arnoud S. Everhardt, Hyeon Jun Lee +8
Optical excitation perturbs the balance of phenomena selecting the tilt orientation of domain walls within ferroelectric thin films. The high carrier density induced in a low-strai…
Nanosecond Optically Induced Phase Transformation in Compressively Strained BiFeO3 on LaAlO3
Youngjun Ahn, Anastasios Pateras, Samuel D. Marks +9
Above-bandgap optical illumination induces a transformation from tilted tetragonal-like (T-like) and rhombohedral-like (R-like) phases to an untilted T-like phase in compressively…
Effects of biaxial strain on the improper multiferroicity in h-LuFeO3 films
Kishan Sinha, Yubo Zhang, Xuanyuan Jiang +11
Elastic strain is potentially an important approach in tuning the properties of the improperly multiferroic hexagonal ferrites, the details of which have however been elusive due t…
Room Temperature Ferroelectricity in Continuous Croconic Acid Thin Films
Xuanyuan Jiang, Haidong Lu, Yuewei Yin +10
Ferroelectricity at room temperature has been demonstrated in nanometer-thin quasi 2D croconic acid thin films, by the polarization hysteresis loop measurements in macroscopic capa…
Inelastic scattering of broadband electron wave packets driven by an intense mid-infrared laser field
A. D. DiChiara, E. Sistrunk, C. I. Blaga +3
Intense, 100 fs laser pulses at 3.2 and 3.6 um are used to generate, by multi-photon ionization, broadband wave packets with up to 400 eV of kinetic energy and charge states up to…
