This article reviews the basic theoretical aspects of graphene, a one-atom-thick allotrope of carbon, with unusual two-dimensional Dirac-like electronic excitations. The Dirac electrons can be controlled by application of external electric and magnetic fields, or by altering sample geometry and/or topology. The Dirac electrons behave in unusual ways in tunneling, confinement, and the integer quantum Hall effect. The electronic properties of graphene stacks are discussed and vary with stacking order and number of layers. Edge (surface) states in graphene depend on the edge termination (zigzag or armchair) and affect the physical properties of nanoribbons. Different types of disorder modify the Dirac equation leading to unusual spectroscopic and transport properties. The effects of electron-electron and electron-phonon interactions in single layer and multilayer graphene are also presented.

Sensitive Room-Temperature Terahertz Detection via Photothermoelectric Effect in Graphene

In percolating networks of mixed metallic and semiconducting CNTs, there is a tradeoff between high on-current (dense networks) and high on/off ratio (sparse networks in which the metallic CNT fraction is not percolating). Experiments on devices in a transistor configuration and Monte Carlo simulations were performed to determine the scaling behavior of device resistivity as a function of channel length (L) for CNT density p in the range 0.04 - 1.29 CNT/{\mu}m^2 in the on- and off-states. Optimized devices with field-effect mobility up to 50 cm^2/Vs at on/off ratio > 10^3 were obtained at W = 50 {\mu}m, L > 70 {\mu}m for p = 0.54 - 0.81 CNTs/{\mu}m^2.

Optimizing Transistor Performance of Percolating Carbon Nanotube Networks

Superconducting diode eﬀect, in analogy to the nonreciprocal resistive charge transport in semiconducting diode, is a nonreciprocity of dissipationless supercurrent. Such an exotic phenomenon originates from intertwining between symmetry-constrained supercurrent transport and intrinsic quantum functionalities of helical/chiral superconductors. In this article, research progress of superconducting diode eﬀect including fundamental concepts, material aspects, device prospects, and theoretical/experimental development is reviewed. First, fundamental mechanisms to cause superconducting diode eﬀect including simultaneous space-inversion and time-reversal symmetry breaking, magnetochiral anisotropy, interplay between spin-orbit interaction energy and the characteristic energy scale of supercurrent carriers, and ﬁnite-momentum Cooper pairing are discussed. Second, the progress of superconducting diode eﬀect from theoretical predictions to experimental observations are reviewed. Third, interplay between various system parameters leading to superconducting diode eﬀect with optimal performance is presented. Then, it is explicitly highlighted that nonreciprocity of supercurrent can be characterized either by current-voltage relation obtained from resistive direct-current measurements in the metal-superconductor ﬂuctuation region ( T ≈ T c ) or by current-phase relation and nonreciprocity of superﬂuid inductance obtained from alternating-current measurements in the superconducting phase ( T < T c ). Finally, insight into future directions in this active research ﬁeld is provided with a perspective analysis on intertwining between band-topology and helical superconductivity, which could be useful to steer the engineering of emergent topological superconducting technologies.

On page 4684, C. Dames, L. Hu and co-workers report highly efficient, broadband lighting from printed hybrid nanocarbon structures with carbon nanotubes and reduced graphene oxides. The fast response and excellent stability of the flexible lighting can find applications in a range of emerging applications where the shape and format, as well as being lightweight, are important.

We have investigated ab-plane thermal conductivity in single crystals of Bi 2 Sr 2 CaCu 2 O 8 in the mixed state. We find that the ab-plane thermal conductivity, кab, below Tc depends on the magnitude and orientation of the magnetic field. A simple empirical expression was found for кab H θ c ), which suggests that electron component of кab is responsible for the normal state behavior of the ab-plane thermal conductivity. However, the к anomaly in the superconducting state is attributed to an increase in its phonon component and a rapid decrease of quasiparticle scattering below Tc.
