“…As R xx and R yy are measured using the same contacts, the measured anisotropy in mobility and conductivity cannot result from different contact resistances, but is intrinsic to the device. Such strong electronic anisotropy is reproduced in three high mobility devices, in agreement with prediction from band structure calculations [51][52][53][54][55][56] and prior experiments 43 .…”

As a high mobility two-dimensional semiconductor with strong structural and electronic anisotropy, atomically thin black phosphorus (BP) provides a new playground for investigating the quantum Hall (QH) effect, including outstanding questions such as the functional dependence of Landau level (LL) gaps on magnetic field B, and possible anisotropic fractional QH states. Using encapsulated few-layer BP transistors with mobility up to 55 000 cm/(V s), we extracted LL gaps over an exceptionally wide range of B for QH states at filling factors -1 to -4, which are determined to be linear in B, thus resolving a controversy raised by its anisotropy. Furthermore, a fractional QH state at ν ≈ -4/3 and an additional feature at -0.56 ± 0.1 are observed, underscoring BP as a tunable 2D platform for exploring electron interactions.

“…Using different procedures of alkali doping it has been recently found that p-Terphenyl K x C 18 H 14 shows a transition from an insulating transparent phase to an inhomogeneous metallic black phase which shows a superconductive behavior with critical temperature T c ranging from few degrees up to 123 Kelvin in different samples [1][2][3][4][5][6][7]. It has been proposed that the amplification of critical temperature reaching a record for metallic aromatic hydrocarbons is driven by the shape resonance belonging to the class for Fano Feshbach resonances in superconducting gaps [8].…”

The recent discovery of superconductivity in a metallic aromatic hydrocarbon, alkali-doped p-Terphenyl, has attracted considerable interest. The critical temperature T c ranges from few to 123 K, the record for organic superconductors, due to uncontrolled competition of multiple phases and dopants concentrations. In the proposed mechanism of Fano resonance in a superlattice of quantum wires with coexisting polarons and Fermi particles, the lattice properties play a key role. Here we report a study of the temperature evolution of the parent compound p-Terphenyl crystal structure proposed to be made of a self-assembled supramolecular network of nanoscale nanoribbons. Using temperature dependent synchrotron radiation x-ray diffraction we report the anisotropic thermal expansion in the ab plane, which supports the presence of a nanoscale network of one-dimensional nanoribbons running in the b-axis direction in the P21/a structure. Below the enantiotropic phase transition at 193 K the order parameter of the C-1 structure follows a power law behaviour with the critical exponent α = 0.34±0.02 and the thermal expansion of the a-axis and b-axis show major changes supporting the formation of a two-dimensional bonds network. The large temperature range of the orientation fluctuations in a double well potential of the central phenyl has been determined.

Abstract. On the background of global warming, energy shortages and environmental pollution, people pay more attention to the low-carbon economy. In this paper, the problem of green supplier selection based on low-carbon economy is studied. Concretely, an evaluation index system for green supplier selection under the low-carbon economy is presented, and then a multi-attribute decision model of green supplier selection is established based on the method of analytic hierarchy process (AHP). This model provides decision reference for the department of supply chain management.
