Here, we report the performance of vacancy affected supercell of a hybrid Graphene-Boron Nitride embedded armchair nanoribbon (a-GNR-BN) based n-MOSFET at its ballistic transport limit using Non Equilibrium Green's Function (NEGF) methodology. A supercell is made of the 3p configuration of armchair nanoribbon that is…
We present numerical simulations that we have performed with the aim of interpreting the results of the transport measurements that we have recently obtained on a graphene device in which a cavity-shaped potential, orthogonal to the transport direction, had been induced with electrostatic lithography. The resistance o…
Abstract The objective of this study was to produce natural fiber –plastic composite using soy straw powder as reinforcing component and to investigate the effect of nano-clay particles addition on the mechanical properties of the composite. Two levels of soy straw powder (35 and 45%) based on the weight of the compos…
Abstract In this article, we present how alignment layers affect blue phase liquid crystals and how we can use this effect to our advantage.
Plasmonics - the interaction of light with free electrons in metals - is commonly understood within classical electrodynamics using local-response constitutive laws (such as Ohm's law). However, the tight localization of plasmons to small volumes is revealing intriguing new physics such as nonclassical electrodynamics…
The 2013 Best Student Paper Award was awarded to Vrashank Shukla, University of Illinois at Urbana-Champaign (Advisor: Elyse Rosenbaum, University of Illinois at Urbana-Champaign) and Co-Authors: Gianluca Boselli, Mariano Dissegna, Charvaka Duvvury, Raj Sankaralingam, Texas Instruments, Inc. for "Predictive Modeling o…
Chitosan is known as a natural polymer which improves strengths of papers. So, in this study investigated improvement of chitosan absorption on modified craft fibers and increase its efficiency. The effects of chitosan were experimented in three levels of 0%, 0.75% and 1.25% on modified kraft fibers surfaces with 3% h…
Mexican hat shaped dispersions are relatively common in few-layered two-dimensional materials. In one to four monolayers of the group-ill chalcogenides (GaS, GaSe, InS, InSe) the valence band undergoes a band inversion from parabolic to a Mexican hat dispersion [1]. This Mexican hat dispersion results in a singularity…
Using first principles Density Functional Theory (DFT) calculations, we have studied the structural and lattice vibrational properties of [111]-oriented Si/Ge core-shell nanowires. Our results show that the fundamental atomicity of the underlying lattice is important for an accurate explanation of phonon frequencies.…
The 2014 Friendship Award In Recognition of Best Paper 2013 ESD-Forum Berlin, Germany was presented to Stanislav Scheier, TU Dortmund University and co-author Stephan Frei, TU Dortmund University for "Analysis of ESD-Robustness of Multi-Layer Ceramic Capacitors in System Applications."
Масса элементарной частицы есть отношение количества материи, содержащейся в крупице материи к ее диаметру. Количество материи, содержащейся в элементарной частице равно количеству материи, содержащемуся в крупице материи. Эта величина есть минимальное количество материи в природе EUM≡UCN^(-1) μ. Это постоянная величи…
This paper investigates the effects of lattice defects on the hysteresis and ferromagnetic resonance behavior of magnetic antidot arrays. The analysis is performed by means of a micromagnetic numerical approach based on the solution of the Landau-Lifshitz-Gilbert equation. Some results demonstrating the possible use o…
In this work, we analyze the properties of edge states in in-plane heterostructures consisting of adjacent zigzag graphene and Boron Nitride (BN) nanoribbons. In contrast with pure zigzag graphene nanoribbons, where gapless edge states are nearly flat and cannot contribute to the conduction, at graphene/BN interfaces…
Abstract In this paper, we describe the effect of the molecular structure of chiral anisotropic compounds and materials on their mesomorphic and physico chemical properties. Modifications of the molecules via cyclic and bridge fragments or via lateral substituents allowed the preparation and optimization of specific m…
Designing periodic structures with novel properties related to propagation of electromagnetic waves presents interest for applications in antenna technology, dispersion engineering, filtering, signal integrity etc. We consider a periodic structure built in stripline technology and assess the effect of geometry modulat…
Almost all phase transitions are accompanied by some degree of lattice strain, typically varying between a few per mil to a few per cent, but extending to 5–10% for martensitic transitions. It is inevitable, therefore, that there will also be changes in elastic properties and, because the elastic moduli are susceptibi…
Abstract Nachdem in den 1980er‐Jahren im Vorland der Sonderabfalldeponie Malsch in erheblichem Umfang Umweltschäden aufgetreten waren, wurde die Deponie in den Jahren 1992 bis 1995 gesichert. Dazu wurden ein Dränagesystem, eine vollständige Umschließung mittels Dichtwand und eine Oberflächenabdichtung hergestellt. Von…
A process of growing large-area plasmonic-nano-particles-decorated ZnO nanorods on the polycarbonate optical disk substrate was developed, while a corresponding photocatalytic rotational reactor was fabricated. Hydrothermal process was adapted to grow ZnO nanorods perpendicular to the optical disk substrate at relativ…
Cu2ZnSnS4(CZTS) absorber layer has recently been put under extensive research as a potential replacement of CIGS absorber layer because of its excellent electrical and optical properties. In this work, CdS, ZnS, ZnSe, In2S3and TiO2have been used as buffer layers in a CZTS/Buffer/i-ZnO structure. The use of i-ZnO as a…
Two types of RTSAs are presented, which spectrally decompose a broadband electromagnetic signal in space in real-time. The first system is based on an array of LWA fed using an array of phasers, where the dispersion of the phasers in conjunction with the natural frequency scanning of the leaky-wave antenna enable the…
