Symmetry-breaking and spin-blockage effects on carrier dynamics in single-layer tungsten diselenide
Ro-Ya Liu, Meng-Kai Lin, Peng Chen +10
Understanding carrier creation and evolution in materials initiated by pulsed optical excitation is central to developing ultrafast optoelectronics. We demonstrate herein that the…
Element-selective tracking ultrafast demagnetization process in Co/Pt multilayer thin films by the resonant magneto-optical Kerr effect
Kohei Yamamoto, Souliman El Moussaoui, Yasuyuki Hirata +8
We examined the photo-induced dynamics of ferromagnetic Co/Pt thin films demonstrating perpendicular magnetic anisotropy with element specificity using resonant polar magneto-optic…
Study of photoinduced valence dynamics in EuNi(SiGe) through time-resolved X-ray absorption spectroscopy
Y. Yokoyama, K. Kawakami, Y. Hirata +10
The photoinduced valence dynamics of EuNi(SiGe) are investigated using time-resolved X-ray absorption spectroscopy for Eu -edge. Through the pump-pro…
Ultrafast unbalanced electron distributions in quasicrystalline 30° twisted bilayer graphene
T. Suzuki, T. Iimori, S. J. Ahn +15
Layers of twisted bilayer graphene exhibit varieties of exotic quantum phenomena1-5. Today, the twist angle Θ has become an important degree of freedom for exploring novel states o…
Two-dimensional conducting layer on SrTiO surface induced by hydrogenation
Y. Takeuchi, R. Hobara, R. Akiyama +5
We found that a surface state induced by hydrogenation on the surface of SrTiO(001) (STO) did not obey the rigid band model, which was confirmed by in situ electrical resisti…
Superstructure-induced splitting of Dirac cones in silicene
B. Feng, H. Zhou, Y. Feng +8
Atomic scale engineering of two-dimensional materials could create devices with rich physical and chemical properties. External periodic potentials can enable the manipulation of t…
