  • Spin–orbit coupling in graphene is small, which makes controlling spin currents in this otherwise useful spintronic material difficult. Avsar et al.now demonstrate that combining graphene with few-layer tungsten disulphide increases its spin–orbit coupling by three orders of magnitude

  • Graphene is known to display unique functional properties due to its two-dimensional structure. Here, the authors measure the thermal conductivity of suspended graphene as a function of sample length, finding that thermal conductivity is higher in longer samples as a result of two-dimensional phonons.

  • Graphene/hBN moiré superlattices exhibit a new set of Dirac mini-bands, whose interband transitions—together with free electrons in the ordinary Dirac bands—modify the nature of the plasmons, as revealed by infrared near-field microscopy.

  • The synthesis of surprisingly stable, free-standing single layers of amorphous carbon and their analysis by atomic-resolution imaging could settle a debate about their atomic arrangement and offer unusual electronics applications.

  • The hardness and incompressibility of diamond makes it an ideal material for high-pressure anvil cells. Here, a method for generating static pressure is described in which graphene-coated diamond is heated, forming graphene nanobubbles that trap water at pressures sufficient to etch the surface of diamond.

  • To be able to control the properties of a system that has strong electron–electron interactions using only an external electric field would be ideal, but the material must be thin enough to avoid shielding of the electric field in the bulk material; here pure electric-field control of the charge-density wave and superconductivity transition temperatures is achieved by electrolyte gating through an electric-field double layer transistor in the two-dimensional material 1T-TiSe2.
