Volumetric optical disks comprising multiple data layers have been proposed to multiply recording density. Owing to the presence of out-of-focus data layers, interlayer cross talk is induced in readout. An optical model was developed to study the readout process and the effect of interlayer cross talk on the readout of dual-layer read-only optical disks. Schemes to improve the readout character...

Two-dimensional stacks of dissimilar hexagonal monolayers exhibit unusual electronic, photonic and photovoltaic responses that arise from substantial interlayer excitations. Interband excitation phenomena in individual hexagonal monolayer occur in states at band edges (valleys) in the hexagonal momentum space; therefore, low-energy interlayer excitation in the hexagonal monolayer stacks can be ...

Combining atomically-thin van der Waals materials into heterostructures provides a powerful path towards the creation of designer electronic devices. The interaction strength between neighbouring layers, most easily controlled through their interlayer separation, can have significant influence on the electronic properties of these composite materials. Here, we demonstrate unprecedented control ...

ID No: FC-169 ABSTRACT The continuous fiber reinforced self-healing ceramic composites (shFRC) were proposed as one of the candidate materials for turbine blade [1]. The shFRC consists of three components, which are oxide fiber bundle, oxide matrix and self-healing agent interlayer. As the self-healing is generated at only the interlayer, it is necessary that crack propagation is led into the i...

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...

The formation of transition-metal surface precipitates may occur during sorption to clay minerals under ambient soil conditions. This process may lead to significant longterm stabilization of the metal within the soil profile. However, the rates and mechanisms controlling surface precipitate formation are poorly understood. We monitored changes in the reversibility of Ni sorbed to a clay minera...

The delamination of montmorillonite in water leads to sliming in ore slurry, which is detrimental to mineral flotation and solid/water separation. In this work, the delamination of Na-montmorillonite (Na-MMT) has been restrained by sodium dodecyl sulfate (SDS) or octadecyl trimethyl ammonium chloride (1831) through the adsorption on the edge of the mineral. The experimental results have shown t...

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...
