“…While Sn doping concentration increases the optical band gap of ZnO films decreases. This shift in the optical band gap may be attributed to the band shrinkage effect because of increasing carrier concentration, Benelmadjat et al [26]. The values of Eg obtained of ZnO:Sn films are almost the same values obtained by other group of tin doped ZnO films prepared by sol-gel method [27].…”

In this work, Undoped Zinc Oxide (ZnO) and Sn-doped Zinc Oxide (ZnO:Sn) films have been deposited by sol-gel dip coating method, where the Sn/Zn atomic ratio was 3% and 5% in the solution. The effects of Sn incorporation on morphological, structural and optical properties of ZnO films were investigated. The Scanning Electron Microscopy (SEM) showed that the morphological surface of the films was affected by Sn low doping. The X-Ray Diffraction (XRD) patterns showed that all films have polycrystalline structures, and the doping incorporation has not lead to substantial changes in the structural characteristics of ZnO films. The crystallite size was calculated using the well-known Scherrer's formula and found to be in the range of 23 -40 nm. The measurements from UV-Visible Spectrophotometer (U-Vis) indicated that the highest average optical transmittance in the visible region was related to Undoped ZnO film, then the optical band gap and Urbach energy values of thin films were calculated. The X-Ray Photoelectron Spectroscopy (XPS) has demonstrated that Sn is incorporated in ZnO lattice.

“…The most typical multifunctional semiconductors in this review are silicon and perovskites. Nevertheless, gas adsorption induced photoresponse change was observed in SnO 2 [120], SnSe [121], SnS [122], PW 12 -TiO 2 [123], MoS 2 [124], WS 2 [125], GaS [126], W 18 O 49 [127], LaAlO 3 /SrTiO 3 [128], ZnO [129]- [132], and various materials fabricated into field-effect transistors and metal-semiconductor-metal device structures. The literatures with different focuses commonly discuss how the absorbent gases affect the generation of a photocurrent.…”

We develop a covariant kinetic theory for massive fermions in curved spacetime and external electromagnetic field based on quantum field theory. We derive four coupled semi-classical kinetic equations accurate at O( ), which describe the transports of particle number and spin degrees of freedom. The relation with the chiral kinetic theory is discussed. As an application, we study the spin polarization in the presence of finite Riemann curvature and electromagnetic field in both local and global equilibrium states.
