Electrons inside a conductor are often described as flowing in response to an electric field. This flow rarely resembles anything like the familiar flow of water through a pipe, but three groups describe counterexamples (see the Perspective by Zaanen). Moll et al. found that the viscosity of the electron fluid in thin wires of PdCoO2 had a major effect on the flow, much like what happens in regular fluids. Bandurin et al. found evidence in graphene of electron whirlpools similar to those formed
Light could make semiconductor computers a million times faster or even go quantum. Transition metal dichalcogenides are semiconductors with potential applications in solar cells. Bulk WSe 2 has an optical band-gap of ~1.35 eV with a temperature dependence of −4.6×10−4 eV/K. WSe 2 photoelectrodes are stable in both acidic and basic conditions, making them potentially useful in electrochemical solar cells.
