Light-enhanced gating effect at the interface of oxide heterostructure
Neha Wadehra, Ruchi Tomar, Yuichi Yokoyama +5
In semiconducting materials, electrostatic gating and light illumination are widely used stimuli to tune the electronic properties of the system. Here, we show a significant enhanc…
Soft X-ray Vortex Beam detected by In-line Holography
Yuta Ishii, Kohei Yamamoto, Yuichi Yokoyama +4
We demonstrate the in-line holography for soft x-ray vortex beam having an orbital angular momentum. A hologram is recorded as an interference between a Bragg diffraction wave from…
Hard and soft x-ray photoemission spectroscopy study of the new Kondo system SmO thin film
Shoya Sakamoto, Kenichi Kaminaga, Daichi Oka +15
SmO thin film is a new Kondo system showing a resistivity upturn around 10 K and was theoretically proposed to have a topologically nontrivial band structure. We have performed har…
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…
