Cr, Nb, Cr/Nb, CrN x , NbN CrNbN, and (CrN/NbN) n structures were produced on Si glass substrates, using the d.c. magnetron sputtering technique. Compositional analysis, based binding energies of N, was carried out by means X‐ray photoelectron spectroscopy (XPS). Through Auger electron (AES), depth profiles obtained, allowing to demonstrate multilayers production. Surface morphological characteristics, as roughness grain size, evaluated atomic force microscopy (AFM), revealing very smooth...
We present a study of electrical and optical properties nitrogen‐doped tin oxide thin films deposited on glass by the DC Magnetron Sputtering method. The deposition conditions to obtain p‐type were relative partial pressure between 7% 11% (N 2 and/or O ), total working 1.8 mTorr plasma power 30 W. oxidized after annealing at 250°C for minutes. X‐ray diffraction results showed that as‐deposited exhibit Sn tetragonal structure, annealing, they SnO structure. photoelectron spectroscopy presence...
Non-stoichiometric NbxNy coatings, produced in a reactive sputtering process, were analyzed on the basis of their chemical composition (specifically, nitrogen concentration) and its relationship with electrical conductivity. The bonding configuration examined using X-ray photoelectron spectroscopy (XPS), revealing Nb–N bonds. stoichiometry variation dependence N2 flow was also analyzed, Auger electron (AES). Without exposing samples to air, normal behavior observed; meaning that...
Tin oxide (SnO x ) has been widely used for the fabrication of transparent and flexible devices because its excellent optical electronic properties. In this work, we established a methodology synthesis SnO thin films with p‐type n‐type tunable conductivity by direct currecnt (DC) magnetron sputtering. The changed from to increasing relative oxygen partial pressure (ppO 2 4.8% 18.5% varying working between 1.8 2.5 mTorr. were annealed at 160°C, 180°C, 200°C 30 min promote formation desired...
This paper reports the synthesis of Bi0.93Sm0.07FeO3 system by conventional method solid-state reaction using quenching at room temperature. X-ray diffraction characterization revealed a rhombohedric perovskite structure with spatial group R3c (161) and an impurity phase Bi2Fe4O9. The scanning electron microscopy images show formation homogeneous grains average size 3µm. energy dispersive Spectroscopy (EDS) microanalysis shows percentage samarium incorporated in bismuth ferrite. analysis...
In recent years, flexible electronics have been an area of considerable interest due to the development materials such as transparent semiconductor oxides, which are compatible with substrates. Herein, lithography and magnetron sputtering used fabricate a p–n diode SnO x thin films on polyimide substrate electrical characterization is performed by varying bending cycles. Using specific oxygen concentrations in reactive gas mixture system, p‐SnO 0.8 (8.0% ppO 2 ) n‐SnO 1.2 (18.5% substrates...
