Thermally activated self-lubricating nanolayer coating for cutting tool applications Robin Abraham Koshy The different nitride phases of Cr and Mo were studied as possible candidates in a bi-layered system that would constitute a thermally activated self lubrication coatings for dry cutting applications. The intent was to deposit multilayer films of CrN and Mo2N, where the Mo2N forms a sacrific...

In this work, we present a nanostructure-sensitive crystal plasticity model for the deformation response of nanolaminate composites. The is applied to investigate strength Mg/Nb nanocomposites, wherein Mg phase has either hexagonal close-packed (HCP) or body-centered cubic (BCC) structure. To account explicitly effects layer thickness and biphase interface on crystallographic slip, features har...

Controllable quantized conductance states of TiN/Ti/HfO$_x$/TiN memristors are realized with great precision through a pulse-mode reset procedure, assisted analytical differentiation the condition set which involves critical monitoring measured bias voltage. An intriguing training effect that leads to faster switching is also observed during operation. Detailed analyses on low- and high-resista...

Black phosphorous (BP) is is recently unveiled as a promising two-dimensional direct bandgap semiconducting material. Here, we report the ambipolar field effect transistor behavior of multilayers of BP with ferromagnetic tunnel contacts. We observe a reduced of Schottky barrier < 50 meV by using TiO2/Co contacts, which could be further tuned by gate voltages. Eminently a good transistor perform...

The rapid developments of big data, the internet things, and artificial intelligence have put forward more requirements for memory chips, logic chips other electronic components. This study introduces ferroelectric origin HfO&lt;sub&gt;2&lt;/sub&gt;-based film explains how element doping, defects, stresses, surfaces interfaces, regulate enhance polarization film. It is widely accepted that ferr...

The optical nonlocality in metal-dielectric multilayer metamaterials is characterized experimentally as a function of the angle of incidence with respect to the TE-polarized incident light. The physical mechanism of the difference between the nonlocal effective permittivity and the effective-medium-theory-based effective permittivity depending on the incident angle is theoretically revealed thr...

Finding the wavevectors (eigenvalues) and wavefronts (eigenvectors) in nanostructured metasurfaces is cast as a problem of finding the complex roots of a non-linear equation. A new algorithm is introduced for solving this problem; example eigenvalues are obtained and compared against the results from a popular, yet much more computationally expensive method built on a matrix eigenvalue problem....

We investigate the effects of hydrodynamic nonlocal response in hyperbolic metamaterials (HMMs), focusing on the experimentally realizable parameter regime where unit cells are much smaller than an optical wavelength but much larger than the wavelengths of the longitudinal pressure waves of the free-electron plasma in the metal constituents. We derive the nonlocal corrections to the effective m...
