High-quality WS2 film with the single domain size up to 400 μm was grown on Si/SiO2 wafer by atmospheric pressure chemical vapor deposition. The effects of some important fabrication parameters controlled growth have been investigated in detail, including choice precursors, tube pressure, growing temperature, holding time, amount sulfur powder, and gas flow rate. By optimizing conditions at one we obtained tungsten disulfide domains an average over 100 μm. Raman spectra, atomic force...
Low-dimensional lead-free organic–inorganic hybrid perovskites have gained increasing attention as having low toxicity, ease of processing, and good optoelectronic properties. Seeking for narrow band gap are great importance the development application photoelectric materials. Here, we reported a Sb-based perovskite (MV)[SbI3Cl2], which has one-dimensional inorganic frameworks I-sharing double octahedra. (MV)[SbI3Cl2] shows direct 1.5 eV, displays obvious photoresponse 532 nm light with...
The Dongping gold deposit is a mesothermal lode hosted in syenite. ore petrography and chemistry of the tellurides from alteration zone have been studied detail using optical microscopy, scanning electron probe micro-beam X-ray diffraction facilities. tellurides, consisting mostly calaverite, altaite, petzite tellurobismuthite tetradymite, are irregularly pyrite fractures voids. In bodies, species quantity decrease top downwards, accompanied with lowering fineness, existence exhibits...
Sixty-six passive continental margin basins around the world were compared comprehensively from aspect of seismogeology on basis plate tectonics. According to their textural and structural differences, classified into seven subdivisions, i.e., rifted basin, non-saline faulted depression saline delta reformed basin positive reverse deformed basin. The have been generated with formation Mesozoic Cenozoic Atlantic Indian Oceans they experienced superimposition three prototypes, including...
The Sandaowanzi (>22t Au) and Beidagou (>5t tellurium–gold deposits are located in the northeastern Central Asian Orogenic Belt (Heilongjiang Province, NE China). ore-hosting volcanic rocks unconformably overly monzogranite were intruded by adakitic granodiorite. In this study, we report new-age, geochemical, Sr–Nd–Pb isotopic data to elucidate genetic link between igneous Te–Au mineralization. New-age indicate that local magmatism occurred Early Jurassic (ca. 177.2 Ma) Cretaceous 118.7 −...
SnSe2 field-effect transistor was fabricated based on exfoliated few-layered flake, and its electrical photoelectric properties have been investigated in detail. With the help of a drop de-ionized (DI) water, FET can achieve an on/off ratio as high ~ 104 within 1 V bias, which is ever extremely difficult for due to ultrahigh carrier density (1018/cm3). Moreover, subthreshold swing mobility are both improved ∼ 62 mV/decade 127 cm2 V−1 s−1 at 300 K, results from efficient screening by liquid...
Abstract: The Dexing porphyry copper ore mine is located in the Qin‐Hang metallogenic belt between Yangtze block and Cathaysia block. It a giant China, including 3 districts: Tongchang, Fujiawu Zhushahong. Our analyses of Re molybdenite indicate that ore‐forming material deposits should be mainly mantle‐derived. study fills gap formation time mine, further proves three districts formed simultaneously, about 170 Ma, belonging to early Yanshan period, consistent with granodiorite which are...
The development of photoelectric devices for high integration and miniaturization in the semiconductor industry can be pushed forward by thriving research two-dimensional layered metal dichalcogenides (2D-LMDs). SnS2 nanosheets have an evident photoresponse to both ultraviolet partial visible light, but only with a fair performance limited their atomic-layer thickness. Here, we report convenient simple method dramatically enhance electrical flake. By integrating Au plasmonic nanostructures,...
Abstract Tellurium-rich (Te) adularia-sericite epithermal Au-Ag deposits are an important current and future source of precious critical metals. However, the evolution ore-forming fluids in these masked by traditional bulk analysis quartz oxygen isotope ratios that homogenize fine-scale textures growth zones. To advance understanding Te metals, herein, we use petrographic cathodoluminescence (CL) images such zones to guide high spatial resolution secondary ion mass spectroscopy (SIMS)...
Tellurium (Te)-bearing adularia-sericite epithermal Au-Ag deposits are widely distributed in calc-alkaline magmatic arcs and an important current future source of precious critical metals.The ore-forming fluids these remains unclear due to the lack in-situ isotopic evidence on Au-, Ag-, Te-bearing minerals.To advance understanding evolution Te metals, herein, we combine situ Pb isotope analysis with He, Ne, Ar microthermometric fluid inclusions ore gangue minerals from two Te-rich Te-poor...
Tellurium-bearing low-sulfidation epithermal Au-Ag deposits are significant producers of gold, silver, and potentially strategic elements if mineral processing methods optimized for recovery. Although these generally related to alkaline magmatism, our study documents an unusual occurrence Te-rich systems in the North Heilongjiang Belt northeast China that is spatially temporally associated with calc-alkaline magmatism tectonic extension a continental arc‐setting. In Belt, Te-bearing usually...
Tellurium–gold deposits differ from normal gold mineralization in their significant content of tellurium‐bearing minerals with a close relation between Au and Te. The Guilaizhuang deposit is major tellurium–gold the Shandong Province China, located eastern margin North China Craton. main sulfide this are pyrite, As‐bearing arsenopyrite, chalcopyrite, galena, sphalerite, chalcocite, argentite. Tellurides contain native tellurium, altaite, coloradoite, petzite, calaverite. Here, we investigate...
AbstractThe South Yellow Sea basin in eastern China has experienced a multi-stage tectonic evolution history. The major structures were created when the was foreland during Mesozoic. However geological of not yet been corroborated by direct evidence from underlying basement rocks. Qianliyan Island southern provides an opportunity to study formation and means geochronological geochemical evidence. On Island, rocks are exposed that consist granitic gneiss, felsic gneiss minor mylonite, lenses...
