Low-Voltage and High-Performance Multilayer MoS2 Field-Effect Transistors with Graphene Electrodes.

Abstract: Atomically thin two-dimensional (2D) materials are attractive because they have excellent material properties and channel length scalability. Fabrication of complex structures from these materials is also relatively easy. Accordingly, 2D materials such as molybdenum disulfide (MoS2) have been intensively studied because of their novel properties for advanced electronics and optoelectronics. This study realizes the low-voltage and high-performance field-effect transistors with chemical vapor deposition-grown single layer graphene employed as the thinnest electrode and semiconducting multilayer (ML) MoS2 utilized as a channel material. The two-terminal mobility of graphene-contacted ML MoS2 using 15 nm Al2O3 as the top-gate dielectric layer is 131.2 cm2/(V s) at room temperature, which is higher than that of the previously reported metal/graphene-contacted MoS2. The result demonstrates that van der Waals bonding at the graphene–MoS2 interfaces and high-k dielectric provide an important step toward the reali...

A study of metallurgy and erosion in laser surface alloying of AlxCu0.5FeNiTi high entropy alloy

Abstract: AlxCu0.5FeNiTi high entropy alloy coating is synthesized by premixed high purity Cu, Fe, Ni and Ti powders on AA1050 aluminium substrate by laser surface alloying, with the aim to improve microhardness and erosion rate. Phase constituents, microstructure and microhardness were investigated using X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM), and Vickers Microhardness tester, respectively. The erosion behavior of AlxCu0.5FeNiTi coating is checked using an air jet erosion setup. SEM images show presence of three regions. Percentage compositions of these regions are evaluated using Energy Dispersive Spectroscopy. XRD analysis of AlxCu0.5FeNiTi coating confirmed that these regions are a mixture of disordered BCC and two FCC solid solution phases. The microhardness of the AlxCu0.5FeNiTi HEA is 18 times that of the AA1050 aluminium substrate. Results show that AlxCu0.5FeNiTi HEA coating has improved erosion resistance.
