 In the wave scattering from rough surfaces investigated by using the surface morphology and the vertical AFM, in general the correct and complete results cannot be obtained. If the roughness with respect to the wavelength is more than a critical limit, the theoretical calculation is not the same as the experimental data, and this inequality cannot be corrected without considering the shadowing...

η-Mo4O11 is a layered metal that undergoes two charge density wave (CDW) transitions at 109 K and 30 K, and is unique in showing a bulk quantum Hall effect [1]. Research so far indicates that this material has a “hidden one-dimensional” (hidden-1d) Fermi surface (FS) in the normal state (T > 109 K), whose nesting property drives the 109 K CDW formation [2]. Here, we directly confirm this pictur...

Localized surface plasmon resonance (LSPR) properties of metallic nanostructures, such as gold, are very sensitive to the dielectric environment of the material, which can simply be adjusted by changing its shape and size through modification of the synthesizing process. Thus, these unique properties are very promising, particularly for the detection of various types of chemicals, for example b...

The photogalvanic effect -- a rectified current induced by light irradiation requires the intrinsic symmetry of medium to be sufficiently low, which strongly limits candidate materials for this effect. In work we explore how in Weyl semimetals can enabled and controlled design material surface. Specifically, provide theory ballistic linear circular semimetal spatially confined slab under genera...

a large number of single research studies on the effects of strategy-based instruction (sbi) in teaching english as a foreign or second language has been conducted so far. however, the lack of a comprehensive meta-analysis targeting the effectiveness of english language sbi is observed. moreover, the findings of experimental studies regarding the context of the english language, proficiency lev...
