Zinc sulfide (ZnS) (3.7 eV band gap) deposited via chemical bath deposition (CBD) has been used previously as a buffer layer material in copper indium gallium selenide (CIGS)-based PVswith reported power conversion efficiency of 16.9%, equaling the p...…
The chemical doping of monolayer MoS2 film over a 13 cm2 area for developing photodetector devices was reported by Kim et al.. The n-type MoS2 semiconductor transitions into the p-type semiconductor after doping with Nb. Raman spectroscopy, X-ray pho...…
As discussed above, the performance of MoS2 photodetectors can be significantly increased by doping MoS2 layers with APTES,180 rhodamines 6G181, and ZnPc182 organic dyes, which efficiently generate charge transfer interfaces between MoS2 and chemical...…
For example, Kang et al. demonstrated that the field-effect mobility increased from 28.75 cm2 V−1 s−1 to 142.2 cm2 V−1 s−1, and the photoresponsivity increased from 219 A W−1 to 5.75 × 103 A W−1 for APTES/MoS2 hybrid phototransistors after aminopropy...…
What is silica?Silicon is one of the most abundant elements in the Earth's crust, the second most abundant after oxygen. Silica is a compound that is important for human Nutrition and health. It is found mainly in bones, nails, hair, and hoof tissue....…
The results show that a coating layer is formed on the surface of boron powder after being coated by the coating agent. The pH value of boron powder and water suspension system increases obviously after coating, which is suitable for the pharmaceutic...…
What is boron powder?Boron powder is a solid black powder. It has a melting point of 2360℃, a boiling point of about 2700℃, a specific gravity of 2.4, and a Mohs hardness of 9.3. It was heated in the air to 900℃ combustion, at 850℃ with molten sodium...…
Zinc sulfide, chemical formula ZnS. The chemical bond property between Zn and S is inclined to covalent bond type. The crystal has three different configurations: low-temperature Type, namely sphalerite structure, which is abundant in nature. Colorle...…
Hydroxypropyl methylcellulose (HPMC) is an organic macromolecule compound commonly used as a water-soluble film-coating agent with good chemical stability. Appearance: White or almost white fibrous or granular powder Stability: Solid is flammable and...…
When heated, molybdenum sulfide can react with chlorine gas to produce molybdenum pentachloride: 2 MoS2+7 Cl2 → 2 MoCl5+2 S2Cl2. Molybdenum disulfide reacts with alkyl lithium under controlled conditions to form an intercalated (interlayer compound) ...…
Currently, only a few countries in the world, such as China, Japan, South Korea, and the United States, have the production capacity of silica fume. The market for silica fume in China is mainly domestic. The silica fume industry is a capital, techno...…
What is the difference between CuO and Cu2O?CuO is copper oxide, and Cu2O is cuprous oxide. Copper oxide is insoluble in water and ethanol, soluble in acid, ammonium chloride and potassium cyanide solution, slowly soluble in ammonia solution, and can...…
