Application of molybdenum foil in two-dimensional rhenium sulfide - molybdenum sulfide preparation
Ultrathin two-dimensional semiconductor materials, such as transition metal disulfide (TMDs), black phosphorus, boron nitride (BN), etc., have excellent optical and electrical properties, which makes them have considerable application prospects in field effect transistors, photodetectors, light-emitting diodes, energy and other fields. Compared with bulk materials, thin-layer 2D transition metal disulfide (TMDs) represented by molybdenum disulfide (MoS2) have very excellent optical and electrical properties, such as layer number dependent indirect to direct bandgap transition, adjustable bandwidth, high light emission efficiency, abundant excitons, and good flexibility. However, it is difficult to control the interlayer exciton and charge transfer with a single two-dimensional TMDs material, which greatly limits their application in the field of high performance and low energy consumption ultra-thin optoelectronic devices. In order to further study the intrinsic photoelectric properties of materials and expand their application fields, researchers have turned their attention to two-dimensional TMD-based vertical heterostructures.
Rhenium sulfide/molybdenum sulfide vertical heterostructures were prepared by chemical vapor deposition. Using Si/SiO2 as substrate, rhenium foil as rhenium source, molybdenum foil as molybdenum source, sulfur powder as sulfur source; The oxidized metal rhenium foil is laid on the surface of one end of the oxidized metal molybdenum foil, the end is close to the sulfur source temperature zone, the substrate is inverted above the metal molybdenum foil, the substrate is close to the sulfur source end with quartz column support, the other end contact with the metal molybdenum foil, quartz boat is located in the precipitation temperature zone; Molybdenum source was molybdenum foil oxidized in air at 350 ° C for two hours, and rhenium source was rhenium foil oxidized in air at 350 ° C for two hours. The quality purity of molybdenum foil is 99.99%. The quality purity of metallic rhenium foil is 99.99%.
