Core–shell behavior and exchange bias of Fe-doped CuO nanoparticles
(2020) [Artigo de periódico]Cu1−xFexO nanoparticles were prepared using a freeze-drying process followed by heat treatment. The particles were then characterized using Mössbauer spectroscopy and magnetization techniques. The results revealed complex ... -
Defects controlling electrical and optical properties of electrodeposited Bi doped Cu2O
(2018) [Artigo de periódico]Doping leading to low electrical resistivity in electrodeposited thin films of Cu2O is a straightforward requirement for the construction of efficient electronic and energy devices. Here, Bi (7 at. %) doped Cu2O layers ... -
Direct observation of multivalent states and 4f → 3d charge transfer in Ce-doped yttrium iron garnet thin films
(2017) [Artigo de periódico]Due to their large magneto-optic responses, rare-earth-doped yttrium iron garnets, Y3Fe5O12 (YIG), are highly regarded for their potential in photonics and magnonics. Here, we consider the case of Ce-doped YIG (Ce-YIG) ... -
Effects of heavy Si doping on the structural and optical properties of n-GaN/AlN/Si(111) heterostructures
(2022) [Artigo de periódico]n-GaN/ AlN heterostructures were grown by molecular beam epitaxy on Si(111)substrates.The GaN films were n-type doped with silicon and the effect of doping concentration on the structural and optical properties was studied. ... -
Electrodeposited Cu2O doped with Cl : electrical and optical properties
(2018) [Artigo de periódico]For understanding the electrical and optical properties of electrodeposited Cl-doped Cu2O thin films, we have studied layers with increasing thickness and Cl concentrations of 0.8 and 1.2 at. %. The deposits were characterized ... -
Growth of boron-doped few-layer graphene by molecular beam epitaxy
(2018) [Artigo de periódico]We investigated the growth of boron-doped few-layer graphene on a-Al2O3 (0001) substrates by molecular beam epitaxy using two different growth approaches: one where boron was provided during the entire graphene synthesis ... -
Heavily n-doped Ge : low-temperature magnetoresistance properties on the metallic side of the metal–nonmetal transition
(2020) [Artigo de periódico]We report here an experimental and theoretical study on the magnetoresistance properties of heavily phosphorous doped germanium on the metallic side of the metal–nonmetal transition. An anomalous regime, formed by negative ... -
Influence of the thermal processing and doping on LaMnO3 and La0.8A0.2MnO3 (A = Ca, Sr, Ba) perovskites prepared by auto-combustion for removal of VOCs
(2022) [Artigo de periódico]Single-phase oxygen stoichiometric LaMnO3 and doped La0.8A0.2MnO3 (A = Ca, Sr, Ba) perovskites have been prepared by a simple one-step auto-combustion method. Cation-deficient LaMnO3+δ and La0.8A0.2MnO3+δ were obtained by ...
