The XRD, Raman, XPS, and EDAX results strongly confirmed the presence of desired phases of MoO3 and gamma-In2Se3 layers in heterostructure without forming any impurity or alloy. FESEM micrographs revealed a uniform, dense grain structure. Optical analysis of MoO3/gamma-In2Se3 done by UV-...
Gamma-in2se3Cu(inga)se-2Co-evaporationSolar-cellsCrystal-structureEfficiencyIn2se3Cu(In,Ga)Se-2 (CIGS) films were elaborated in a new 'two stages' process using gamma-ln(2)Se(3) as thin film precursor. The first stage consists on the elaboration of this precursor and in the second Cu...
The energy relaxation of electrons in gamma-In2Se3 nanorods was investigated by the excitation-dependent photoluminescence (PL). From the high-energy tail of PL, we determine the electron temperature (T (e)) of the hot electrons. The T (e) variation can be explained by a model in which ...
gamma-In2Se3 phaseIn the present report, we have studied the structural and optical change in the In2Se3 thin films prepared by the thermal evaporation method, deposited on a glass substrate and annealed at 250 degrees C. Both the structural and optical studies revealed the formation of gamma...
The invention provides a preparation method of a gamma-In2Se3 film with (006) preferred direction and belongs to the technical field of materials. The preparation method comprises the following steps: A, cleaning a substrate; B, sputtering an In2Se3 film: namely mounting a high-purity indium-...
The crystallization of the as-deposited films was performed by post-deposition heat treatment in neutral atmosphere. Photoconductivity measurements were performed on films of both compounds in order to study the effect of crystalline quality and Te on the photoconductive behaviour of the films. It has...
In this work, we present the assembly of a gamma-In2Se3/GaAs heterostructure-based photodetector linear array composed of 1 x 10 device units. The layered gamma-In(2)Se(3)films with a well-defined pattern are deposited directly onto a planar GaAs substrateviaradio-frequency (RF) magnetron ...
Crystals grown in the direction of high-energy facets have reduced surface energy, a small portion of high-energy crystal facets, and high photocatalytic activity. In this work, gamma-In2Se3 nanoparticles with predominantly exposed {110} facets are synthesized hydrothermally in the presence of ...
The In2Se3 films on (111) Si substrate were pinhole-free with homogeneous and lamellar structures. It was found that by properly controlling the substrate temperatures, single-phase gamma-In2Se3 films with fairly good optical properties can be well fabricated. Photoluminescence spectra, of single-...
