We propose the model of layered materials, in which each layer is described by conventional Haldane model, while inter-layer hopping parameter corresponds to ABC stacking. calculate topological invariant N3 for resulting responsible conductivity intrinsic quantum Hall effect. It has been shown that a finite value interlayer parameter, equal number layers multiplied layer. At same time this may ...
In this paper, a multilayer perceptron guided key generation for encryption/decryption (MLPKG) has been proposed through recursive replacement using mutated character code generation for wireless communication of data/information. Multilayer perceptron transmitting systems at both ends accept an identical input vector, generate an output bit and the network are trained based on the output bit w...
An x-ray multilayer mirror, specially designed to produce resonant absorption at a definite angle of incidence, may be used as an angular dispersive element for refractive x-ray radiography. In this method the signal-to-noise ratio can be significantly enhanced due to suppression of the shot noise produced by the direct beam. Refraction contrast of a copper wire 75 μm in diameter and a human ha...
We study the thermal behaviour of a tri-layer multilayer, designed by inserting a third material, yttrium, into the previously studied Co/Mo2C system. The system is designed to work at near-normal incidence at the wavelength of 14.1 nm. The theoretical reflectivity of Co-based multilayer (Co/Mo2C/Y system) is improved up to 54% after the addition of yttrium. Two types of multilayers with differ...
