作者： Shintaro Komaba Nana Taketa Meita Asami Masakazu Sugiyama Tetsuo Ikari Atsuhiko Fukuyama Faculty of Engineering University of Miyazaki 1-1 Gakuen-Kibanadainishi Miyazaki Japan Research Center for Advanced Science and Technology The University of Tokyo

We investigated photoexcited carrier transition in Wire-on-Well (WoW) structures using photoluminescence and photoreflectance measurements. The observed low-temperature photoluminescence peaks showed a blue shift when the excitation power was increased. This result is explained by considering recombination between the quantum states of spatially separated positions in quantum wells of WoW structures.

High-efficiency electrocatalysis could serve as the bridge that connects renewable energy technologies,hydrogen economy and carbon capture/utilization, promising a sustainable future for humankind. It is therefore of paramount significance to explore feasible strategies to modulate the relevant electrocatalytic reactions and optimize device performances so as to promote their large-scale practical *** regulation at the catalytic interface has been demonstrated to be capable of effectively enhancing the reaction rates and improving the selectivities for specific products. In this review we summarize the latest advances in microenvironment regulation in typical electrocatalytic processes(including water electrolysis, hydrogen–oxygen fuel cells, and carbon dioxide reduction) and the related in situ/operando characterization techniques and theoretical simulation methods. At the end of this article, we present an outlook on development trends and possible future directions.

Using lateral spin transport measurements, we experimentally estimate the spin diffusion length (λ) and spin lifetime (τ) in strained n-Si0.1Ge0.9 with two-different carrier concentrations (n) of ~1×1018 cm-3 and ~5×1018 cm-3 in the temperature range from 8 K to room temperature. We find a marked difference in τ depending on n at temperatures less than 100 K. We propose that, in the degenerate regime, the intravalley spin-flip scattering mechanism should be considered in the strained n-Si0.1Ge0.9 © 2023 IEEE.

We demonstrate field-induced single-ion magnetic anisotropy resulting from the multiorbital Kondo effect on the diluted ytterbium alloy (Lu1−xYbx)Rh2Zn20. Single-ion anisotropic metamagnetic behavior is revealed in low-temperature regions where the local Fermi-liquid state is formed. Specific heat, low-field magnetic susceptibility, and resistivity indicate reproduction of the ground-state properties by the SU(N=8) Kondo model with a relatively large c−f hybridization of TK=60.9K. Dynamical susceptibility measurements on YbRh2Zn20 support realizing the multiorbital Kondo ground state in (Lu1−xYbx)Rh2Zn20. The single-ion magnetic anisotropy becomes evident above ∼5T, which is lower than the isotropic Kondo crossover field of 22.7 T, verifying blurred low-lying crystal field states through the multiorbital Kondo effect.
