“…25,26 Moreover, the strong SOC effect and the breaking of inversion symmetry for monolayer TMDs also promote the research works on their spintronic applications, especially for the generation of SOT. [27][28][29] Current induced field-like and damping-like torques were observed in Py/MoS2 bilayers and the strong SOT exhibited purely interfacial nature. 30 A further study has experimentally shown that one can change the allowed symmetries of SOT in spin-source/ferromagnet bilayer devices with low crystalline symmetry.…”

Transition metal dichalcogenides (TMDs) have drawn great attention owing to their potential for electronic, optoelectronic and spintronics applications. In TMDS/ferromagnetic bilayers, efficient spin current can be generated by the TMDs for the manipulation of magnetic moment in the ferromagnetic layer. In this work, we report on the electric-field modulated spin-orbit torques (SOT) in WS2/NiFe (Py) bilayers by spintorque ferromagnetic resonance technique (ST-FMR). It is found that the RF current can induce a spin accumulation at WS2/Py interface due to the interfacial Rashaba-Edelstein effect. More importantly, the SOT ratio between field-like torque and anti-damping-like torque can be effectively controlled by applying back-gate voltage in WS2/ NiFe bilayers.

“…Moreover, in a phosphorene ribbon, the edges terminated with zigzag or armchair configuration as well as functional groups have a different bandgap as compared to its microscale counterpart. The ease of bandgap tunability in phosphorene renders it a rich platform for novel physical phenomena such as the integral quantum hall effect, superconductivity, fermions, spintronics, and topological insulators …”

Black phosphorus was first synthesized by Bridgman in 1914 [1] but has been less intensively studied in the past century due The successful isolation of phosphorene (atomic layer thick black phosphorus) in 2014 has currently aroused the interest of 2D material researchers. In this review, first, the fundamentals of phosphorus allotropes, phosphorene, and black phosphorus, are briefly introduced, along with their structures, properties, and synthesis methods. Second, the readers are presented with an overview of their energy applications. Particularly in electrochemical energy storage, the large interlayer spacing (0.53 nm) in phosphorene allows the intercalation/deintercalation of larger ions as compared to its graphene counterpart. Therefore, phosphorene may possess greater potential for high electrochemical performance. In addition, the status of lithium ion batteries as well as secondary sodium ion batteries is reviewed. Next, each application for energy generation, conversion, and storage is described in detail with milestones as well as the challenges. These emerging applications include supercapacitors, photovoltaic devices, water splitting, photocatalytic hydrogenation, oxygen evolution, and thermoelectric generators. Finally the fast-growing dynamic field of phosphorene research is summarized and perspectives on future possibilities are presented calling on the efforts of chemists, physicists, and material scientists

PtTe 2 is a novel transition-metal dichalcogenide hosting type-II Dirac fermions that displays application capabilities in optoelectronics and hydrogen evolution reaction. Here it is shown, by combining surface science experiments and density functional theory, that the pristine surface of PtTe 2 is chemically inert toward the most common ambient gases (oxygen and water) and even in air. It is demonstrated that the creation of Te vacancies leads to the appearance of tellurium-oxide phases upon exposing defected PtTe 2 surfaces to oxygen or ambient atmosphere, which is detrimental for the ambient stability of uncapped PtTe 2 -based devices. On the contrary, in PtTe 2 surfaces modified by the joint presence of Te vacancies and substitutional carbon atoms, the stable adsorption of hydroxyl groups is observed, an essential step for water splitting and the water-gas shift reaction. These results thus pave the way toward the exploitation of this class of Dirac materials in catalysis.
