We report on spin ratchet currents driven by terahertz radiation electric fields in a Co/Pt magnetic metamaterial formed triangle-shaped holes forming an antidots lattice and subjected to external field applied perpendicularly the metal film plane. show that for wavelength substantially larger than period of array causes polarization-independent spin-polarized current. The current is generated periodic asymmetric intensity distribution caused near-field diffraction at edges antidots, which...
Abstract We investigated the C-related complexes in highly C-doped GaN by electron spin resonance (ESR) spectroscopy, Fourier transform IR spectroscopy (FTIR), and minority carrier transient (MCTS) measurements. In ESR spectra, two resonances with g values of 2.02 2.04 were found to be assigned (0/−) deep acceptor (+/0) charge transition levels carbon substituting for nitrogen site (C N ). FTIR local vibrational modes positioned at 1679 1718 cm −1 confirmed associated tri-carbon C –C Ga...
It has been recognized that many caregivers of dementia patients have sleep problems, and these problems are often related to the nighttime behaviors care recipients. Recent studies found approximately two-thirds suffer from disturbances, poor quality caregiver is linked not only physical psychological burdens but also an increased risk depression. This study aimed investigate whether well-being mediated by its relationship behavioral symptoms in elderly relatives using a mediational model....
Abstract The semiconductor photocathode with AlGaAs/GaAs superlattice structures, which is a highly durable electron beam source low energy dispersion, were grown by molecular epitaxy. sample showed step-like quantum efficiency spectrum of photoelectron emission, indicating its applicability to photocathodes. optimization room temperature photoluminescence provides the improvement up 0.5%, promising for further and realistic applications.
In 2005, the proportion of care workers in Japanese labor force was 1.7%. By 2025, is projected to increase 3.4–4.4%. However, many are leaving their jobs because low wages and/or excessive burden. Therefore, this study aimed investigate work-related stress and mental health status elucidate impact on psychological distress. The participants were staff who working at facilities. Self-administered questionnaires used collect information about demographic factors, conditions, self-rated...
