Improved efficiency of organic solar cells using Au NPs incorporated into PEDOT: PSS buffer layer
(AIP Publishing LLC, 2017)
Au based plasmonic phenomenon inside the hole transport layer poly(3,4-
ethylenedioxythiophene)-poly(styrenesulfonate) (PEDOT:PSS) of an organic solar
cell based on blend of poly(3-hexylthiophene) (P3HT) and [6:6]-phen ...
Ab initio study of the structural, vibrational and thermal properties of Ge2Sb2Te5
(Imperial College Press, 2015-06-12)
The structural, vibrational and thermal properties of hexagonal as well as cubic Ge2Sb2Te5 (GST) have been calculated from first principles. The relative stability of the possible stacking sequences of hexagonal GST has ...
The Acoustic Wave Propagation Equation: Discontinuous Galerkin Time Domain Solution Approach
(Hikari Ltd, 2019)
This paper discusses a finite element method, discontinuous Galerkin
time domain approach that solves the 2-D acoustic wave equation in
cylindrical coordinates. The method is based on discretization of the
wave field ...
Photospins in the quantum Rabi model
(Research gate, 2019)
This article provides a systematic interpretation of the quantum Rabi model as a model of
photospins formed in the atom-field Jaynes-Cummings and anti-Jaynes-Cummings interaction
mechanisms. A photospin is a quantized ...
Enhancing light absorption and lifetime stability of organic solar cells using pentacene encapsulation
(SA Institute of Physics, 2015)
. In the present work we compare the performance of a pristine P3HT:PCBM
based bulk heterojunction solar cell with a device incorporated with pentacene encapsulated
Ag nanoparticles. Encapsulation has been achieved through ...
The anti-Jaynes-Cummings model is solvable : quantum Rabi model in rotating and counter-rotating frames ; following the experiments
(Cornell University, 2021)
This article is a response to the continued assumption, cited even in reports and reviews of recent experimental breakthroughs and advances in theoretical methods, that the antiJaynes-Cummings (AJC) interaction is an ...
Optical properties and Raman studies of amorphous Se-Bi thin films
(The African Review of Physics, 2014)
Flash evaporated amorphous Se Bi
(x = 0, 1, 2, 3, and 4 at. %) thin films of 350 ± 10 thickness have been
investigated in the wavelength range of 200nm − 3000nm. It is found that the effect of increasing bismuth ...
Microstructural and elastic properties of stable aluminium-rich TiAl and TiAl2 formed phase Intermetallics
(North-Holland, 2021)
We studied aluminium-rich Ti-Al (Ti32Al68 and Ti40Al60) binary alloys that were composed of TiAl and
TiAl2 lamellar microstructures. The law of mixtures was employed in calculating the theoretical
Young’s moduli. The ...
Compositional and Thickness Effects on the Optical Properties of Zinc–Doped Selenium–Antimony Thin Films
(Tanzania Journal of Science, 2018)
Chalcogenide system of antimony (Sb)-selenium (Se)-zinc (Zn) system is a promising semiconductor for phase change memory devices due to its thermal stability and low power consumption. The study investigated the effect of ...
AN INVESTIGATION OF THE EFFECTS OF BOUNDARY LAYER THICKNESS ON A THIN FILM OF LIQUID FLOW DOWN AN INCLINED PLANE
(2012-12-30)
The motion of fluid substances may be described by the Navier-Stokes (N-S)
equations. The equations arise from the application of Newton’s second Law of
motion to a fluid. In this paper, N-S equations in two dimensions ...
