Deep level transient spectroscopy and pseudopotential superlattice calculation for an InAs monolayer embedded in GaAs
We present deep level transient spectroscopy measurements and pseudopotential supercell calculations for InAs monolayers embedded in GaAs. The insertion of InAs MLs into GaAs generates two states in the...
PublicationsEnhanced field emission from cerium hexaboride coated multiwalled carbon nanotube composite films: A potential material for next generation electron sources
Intensified field emission (FE) current from temporally stable cerium hexaboride (CeB6) coated carbon nanotubes (CNTs) on Si substrate is reported aiming to propose the new composite material as a potential...
PublicationsMicrostructure, electrical, magnetic, and extraordinary Hall effect studies in Ni:SiO2 nanogranular films synthesized by atom beam sputtering
In this work we report on the synthesis of Ni:SiO2 nanogranular films with different metal fraction (0.10≤x≤0.68)and a homogeneous distribution of Ni particles by atom beam sputtering technique and...
PublicationsRole of Coulomb blockade and spin-flip scattering in tunneling magnetoresistance of FeCo-Si-O nanogranular films
In this work, we report the effect of FeCo atomic fraction (0.33<x<0.54) and temperature on the electrical, magnetic, and tunneling magnetoresistance (TMR) properties of FeCo-Si-O granular films...
PublicationsThickness independent magneto-optical coupling constant of nickel films in the visible spectral range
Magneto-optical properties of nominally 10, 20, and 30 nm thick ferromagnetic Ni films have been investigated at room temperature by vector-magneto-optical generalized ellipsometry under saturated magnetization...
PublicationsNovel implementation of memristive systems for data encryption and obfuscation
With the rise of big data handling, new solutions are required to drive cryptographic algorithms for maintaining data security. Here, we exploit the nonvolatile, nonlinear resistance change in BiFeO3 memristors...
PublicationsInfluence of the domain size on the band gap of ordered (GaIn)P
The domain size and the band-gap energy of ordered epitaxial (GaIn)P layers have been determined by means of transmission electron microscopy and photoluminescence measurements, respectively. With decreasing...
PublicationsEnhanced field emission from lanthanum hexaboride coated multiwalled carbon nanotubes: Correlation with physical properties
Detailed results from field emission studies of lanthanum hexaboride (LaB6) coated multiwalled carbon nanotube (MWCNT) films, pristine LaB6 films, and pristine MWCNT films are reported. The films have...
PublicationsHigh cluster formation tendency in Co implanted ZnO
ZnO(0001) single crystals have been implant doped with a maximum of 5 at. % of Co at low temperatures. While as-implanted crystals do not show ferromagnetic properties, postimplantation annealing leads...
PublicationsProbing origin of room temperature ferromagnetism in Ni ion implanted ZnO films with x-ray absorption spectroscopy
We report x-ray absorption at Zn and Ni K-edges in 200 keV Ni2þ ion implanted ZnO/sapphire films. The implantation fluences are 6×1015 and 2×1016 ions/cm2, corresponding to 2% and 7% Ni in a ZnO matrix....
