We discuss a methodology for calculating the interlayer transport characteristics of electron-hole bilayer graphene at spontaneous coherence using path integral Monte Carlo and recursive scattering matrices at room temperature. We find transport characteristics very similar to that of the quantum Hall bilayer case in that there is a large peak in the differential interlayer conductance at low i...

Abstract In this review, we give a brief overview of recently developed montmorillonite-based heterogeneous catalysts used for efficient organic reactions. Cation-exchanged montmorillonite catalysts, metal supported on montmorillonite, and an interlayer design selective catalysis are introduced discussed. traditional syntheses, homogeneous acids salts were as but the difficulty in separation fr...

High Al content AlxGa1-xN/GaN multiple quantum well (MQW) films with different interlayers were grown by metal organic chemical vapor deposition. These MQWs were designed to achieve intersubband (ISB) absorption in the mid-infrared spectral range. We have considered two growth conditions, with AlGaN interlayer and GaN/AlN superlattice (SL) interlayer, both deposited on GaN-on-sapphire templates...

van der Waals homo- and heterostructures assembled by stamping monolayers together present optoelectronic properties suitable for diverse applications. Understanding the details of the interlayer stacking and resulting coupling is crucial for tuning these properties. We investigated the low-frequency interlayer shear and breathing Raman modes (<50 cm(-1)) in twisted bilayer MoS2 by Raman spectr...

We have imaged the magnetic fields at the edges of the conducting planes of a single crystal of the layered organic superconductor κ-(BEDTTTF)2Cu(NCS)2. The spatial dependence of these fields agrees well with a Josephson-coupled layer model with some inhomogeneity in the interlayer coupling, providing a direct measurement of the interlayer coupling strength. This coupling is sufficiently weak a...

Density functional theory (DFT) calculations were employed to investigate the energetics of carbon dioxide migration within hydrated or anhydrous graphene oxides (GOs). When anhydrous GO structures contain a carbon dioxide molecule, the carbon dioxide interacts repulsively with the GO layers to increase the interlayer spacing. The repulsive electrostatic interactions are reduced by the insertio...

The interlayer interaction of vertically stacked heterojunctions is very sensitive to the interlayer spacing, which will affect the coupling between the monolayers and allow band structure modulation. Here, with the aid of density functional theory (DFT) calculations, an interesting phenomenon is found that MoS2-WS2, MoS2-WSe2, and WS2-WSe2 heterostructures turn into direct-gap semiconductors f...

The interlayer bonding strength is an essential property of geogrid-reinforced asphalt. To study the characteristics asphalt, direct shear and oblique tests were carried out in laboratory. interlaminar asphalt was lower than that unreinforced carbon–carbon sample highest, second, carbon–glass lowest. stiffness geogrid affects strength. strengths AC-20C samples higher AC-13C samples. almost same...

We report on the intercalation of a cationic fluorescent oligo(fluorene) in between the 2D interlayer region of a fluoromica type silicate. The formation of intercalated structures with different fluorophore contents is observed in powders by synchrotron radiation XRD. Successively, the hybrids are dispersed in poly(styrene) through in situ polymerization. Such a procedure allows us to synthesi...

By measuring the Josephson Plasma Resonance, we have probed the influence of an in-plane magnetic field on the pancake vortex correlations along the c-axis in heavily underdoped Bi2Sr2CaCu2O8+δ (Tc = 72.4 ± 0.6 K) single crystals both in the vortex liquid and in the vortex solid phase. Whereas the in-plane field enhances the interlayer phase coherence in the liquid state close to the melting li...
