InxGayAl1−x−ySb alloys have been grown by molecular beam epitaxy for use as a buffer layer for growing semiconductors on GaAs substrates with lattice constants beyond that of AlSb. This is an extension of the use of AlxGa1−xSb alloys to accommodate for the lattice mismatch with semi-insulating GaAs substrates. The gro…
In this paper, we report a fast effective mass model for accurately calculating the bound states and optical transitions of self-assembled quantum dots. The model includes the atomistic strain effects, namely, the strain deformation of the band edges, and strain modification of the effective masses. The explicit inclu…
We present vertical split-ring resonators (VSRRs) which behave as magnetic metamolecules sensitive to both the incident electric and magnetic fields upon excitation. A couple of potential applications such as VSRR-based highly sensitive refractive-index sensor and metasurface for light manipulation in optical communic…
Abstract Agglomerates of a few μm of the yellow phosphor La3BaSi5N9O2:Ce3+ are obtained by heating a mixture of LaF3, La(NH2)3, BaH2, Si(NH)2, and CeF3 in a radio frequency furnace under N2 (1600 °C, 10 h; cooling to 900 °C within 44 h).
The functionalization of self-assembled peptide nanostructures with blue-emitting conjugated polymers of the polyfluorene family opens up a new generation of biodegradable materials in organic electronics. In article number 1500265, S. Guha and co-workers demonstrate that the synthesis of diphenylalanine micro-/nanost…
In this paper, we describe the light-plasmonic nanoantennas interactions based on a Volume Integral Equation (VIE) formulation. We especially focus on the standard and non-standard eigenvalue problem for a nanoantenna. Their implementations in a Volumetric Method of Moments algorithm are discussed as well.
This paper presents an adjustable field weakening control method for a high-speed permanent magnet motor (PMM). A compact designed PMM sometimes needs strong field weakening in the high-speed domain. The proposed control method adjusts field weakening to obtain enough torque for stability of 1MW/3.2kV/ 6600rpm-PMM ope…
The application of reduced common mode voltage pulse width modulation methods bring much high order harmonics to the variable speed drive system, which causes considerable iron loss inside the electric motor. In this paper, an improved iron loss model considering those high order harmonics is proposed. Iron loss coeff…
Abstract In this article, we describe the effect of ethanolamine (EA) surface treatment on the inverted InP quantum dot light‐emitting diodes (QD‐LEDs) with inorganic metal oxide layers. The efficiency of the inverted QD‐LEDs was significantly enhanced by EA treatment and optimization of the ZnO annealing temperature.
Fibre supercapacitors were manufactured using a motor-driven setup. Their electrochemical properties were characterised. The performance of two fibre supercapacitors in series or in parallel mainly followed the expected theoretical models. The electrochemical potential window of a series circuit of two fibre supercapa…
This paper proposes a composite right/left-handed (CRLH) cylindrical waveguide. Negative permeability is realized by the cutoff TM01-mode in a hollow waveguide and also negative permittivity is realized by the cutoff dominant TE-mode in a sector waveguide with a ridge. Usefulness of the proposed cylindrical waveguide…
The increase in surface temperature of the large cabinets of power converters, which are typically made of iron materials (with magnetic characteristics), was investigated. For this investigation, a method combining electromagnetic-field analysis and thermal-fluid analysis by using in-house analysis tools was establis…
Concept of edge polarizability produced by support of the edge quantum states is demonstrated by the example of graphene nanoribbon with zigzag edge configuration. This concept allows to formulate physically correct edge conditions for electromagnetic field in nanostructures instead of ordinary Meixner conditions in c…
A novel Frequency Selective Surface (FSS) is proposed for the design of polarization-insensitive metamaterial absorbers that operate around 1 GHz, where the first resonances of small commercial enclosures take place. The novel FSS is based on the simplification of an alternative Roman maze. It shows a strong sub-wavel…

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…
