Journal ArticleDOI
Elastically driven cooperative response of a molecular material impacted by a laser pulse.
Roman Bertoni,Maciej Lorenc,Hervé Cailleau,Antoine Tissot,Jérôme Laisney,Marie-Laure Boillot,Laurentiu Stoleriu,Alexandru Stancu,Cristian Enachescu,Eric Collet +9 more
TL;DR: A self-amplified responsiveness in a spin-crossover material during its delayed volume expansion is demonstrated and it is shown that elastically driven cooperativity triggered by a light pulse offers an efficient route towards the generation and stabilization of photoinduced phases in many volume-changing materials.
Journal ArticleDOI
Photoinduced Stark Effects and Mechanism of Ion Displacement in Perovskite Solar Cell Materials
Meysam Pazoki,T. Jesper Jacobsson,Jolla Kullgren,Erik M. J. Johansson,Anders Hagfeldt,Gerrit Boschloo,Tomas Edvinsson +6 more
TL;DR: For optimized perovskite solar cell devices beyond 19% efficiency, it is shown that excess thermalization energy of blue photons plays a role in overcoming the activation energy for ion diffusion.
Journal ArticleDOI
Nanoscale diffractive probing of strain dynamics in ultrafast transmission electron microscopy.
TL;DR: In this paper, the authors introduced ultrafast convergent beam electron diffraction with a nanoscale probe beam for the quantitative retrieval of the time-dependent local deformation gradient tensor.
Journal ArticleDOI
Giant elastic tunability in strained BiFeO3 near an electrically induced phase transition.
Qian Li,Ye Cao,Pu Yu,Rama K. Vasudevan,Nouamane Laanait,Alexander Tselev,Fei Xue,Long Qing Chen,Petro Maksymovych,Sergei V. Kalinin,Nina Balke +10 more
TL;DR: The giant electrically tunable elastic stiffness and corresponding electromechanical properties observed here suggest potential applications of BiFeO3 in next-generation frequency-agile electroacoustic devices, based on the utilization of the soft modes underlying successive ferroelectric phase transitions.
Journal ArticleDOI
Ultrafast acousto-optic mode conversion in optically birefringent ferroelectrics
Mariusz Lejman,Gwenaelle Vaudel,Ingrid C. Infante,Ievgeniia Chaban,Thomas Pezeril,Mathieu Edely,Guillaume F. Nataf,Mael Guennou,Jens Kreisel,Vitalyi Gusev,Brahim Dkhil,Pascal Ruello +11 more
TL;DR: By allowing the manipulation of light polarization with gigahertz coherent acoustic phonons, this work provides a novel route for the development of next-generation photonic-based devices and highlights new capabilities in using ferroelectrics in modern photonics.
