The existence of a premixed interlayer has direct influence on the reaction kinetics in reactive multilayers. In this study, molecular dynamics simulations are used as tool to study interlayers front propagation and diffusion Al–Ni For this, with different, namely, homogeneous, gradient, s-shaped profiles studied. Comparison existing experimental results further increases understanding nature i...

Light-induced interlayer ultrafast charge transfer in 2D heterostructures provides a new platform for optoelectronic and photovoltaic applications. The charge separation process is generally hypothesized to be dependent on the interlayer stackings and interactions, however, the quantitative characteristic and detailed mechanism remain elusive. Here, a systematical study on the interlayer charge...

We study interlayer transport in double-layered (mmm) quantum Hall liquids in the weak tunneling limit, in particular the effects of lead geometry on the I-V characteristics of interlayer tunneling. We proposed several practical ways to study experimentally the novel interlayer transport properties in the double-layered (mmm) quantum Hall liquids. Some concrete predictions on the DC characteris...

Study on the interlayer has developed associated with in-depth exploration and development of oil fields, which is an indispensable part to characterize reservoir heterogeneity. This study relates to a comprehensive research method of interlayer in rhythmic layering in continental low permeability reservoirs. During the process of waterflooding development, distribution characteristics of inter...

We study the Josephson-like interlayer tunneling signature of the strongly correlated nuT=1 quantum Hall phase in bilayer two-dimensional electron systems as a function of the layer separation, temperature, and interlayer charge imbalance. Our results offer strong evidence that a finite temperature phase transition separates the interlayer coherent phase from incoherent phases which lack strong...

The influence of a thin porous SiNX interlayer on the growth of GaN by metalorganic chemical vapor deposition (MOCVD) has been studied. The interlayer is deposited on a GaN template by introducing silane in the presence of ammonia into the MOCVD chamber, and a GaN overlayer is deposited on the interlayer. The SiNX interlayer produces inhomogeneous nucleation and lateral growth of the overlayer,...

We study the Joshepson-like interlayer tunneling signature of the strongly correlated νT = 1 quantum Hall phase in bilayer two-dimensional electron systems as a function of the layer separation, temperature and interlayer charge imbalance. Our results offer strong evidence that a finite temperature phase transition separates the interlayer coherent phase from incoherent phases which lack strong...

A Permian bentonite deposit at Melo, Uruguay is composed of a calcite-cemented sandstone containing clay pseudomorphs of glass shards (0-0.50 m) overlying a pink massive clay deposit (0.50-2.10 m). The massive bed is composed of two layers containing quartz and smectite or pure smectite respectively. The smectite is remarkably homogeneous throughout the profile: it is a complex mixed layer comp...

Electroluminescence efficiency is crucial for the application of quantum-dot light-emitting diodes (QD-LEDs) in practical devices. We demonstrate that nitrogen-doped carbon nanodot (N-CD) interlayer improves electrical and luminescent properties of QD-LEDs. The N-CDs were prepared by solution-based bottom up synthesis and were inserted as a hole transport layer (HTL) between other multilayer HT...

At small layer separations, the ground state of a nu = 1 bilayer quantum Hall system exhibits spontaneous interlayer phase coherence. The evolution of this state with increasing layer separation d has been a matter of controversy. We report on small system exact diagonalization calculations which suggest that a single-phase transition, likely of first order, separates incompressible states with...
