TL;DR: In this paper, the authors investigated amorphous Sb-based phase-change materials and found that Sb forms shorter and stronger bonds with Se and S than Te, and the average bonding angles of Se (92.0°) and S (94.1°) show larger distortion than that of Te (91.5°).

TL;DR: In this article, the structural, mechanical, electronic, and optical properties of B6O were explored by means of first-principles calculations, such as real and imaginary parts of dielectric functions, refractive index and extinction coefficient, and the comparison of optical properties between the density functional theory (DFT) and G0W0 Bethe-Salpeter equation (G0W 0-BSE) results, were computed and discussed.

TL;DR: In this article, a solar selective absorber with a multilayered SiO2 (87.0 nm)/Cr (8.3 nm)/SiO2(96.3nm) film structure was designed and fabricated by magnetron sputtering on a surface-roughened copper (Cu) substrate.

TL;DR: In this article, the effect of Bi doping in ultrathin Pb(111) films on tuning the quantum size effects (QSEs) of random metal alloy films was investigated.

TL;DR: In this paper, a constructive and effective method of analyzing interfaces by applying two different optical models consisting of air/TiO2/Ti x Si y O2/Si and air/effective TiO2 layer/Si, respectively, was proposed to investigate the influence of interface layer (IL) on the analysis of optical constants and the determination of band gap.
