influence of aluminum, gallium, indium- doping on the boron-nitride nanotubes (bnnts) investigated with density functional theory (dft) and hartreefock (hf) methods. for this purpose, the chemical shift of difference atomic nucleus was studied using the gauge included atomic orbital (giao) approch. in the following, structural parameter values, electrostatic potential, thermodynamic parameters,...

Indium is a typical chalcophile element of the Earth’s crust, with a very low average content that seldom forms specific minerals, occurring mainly as dispersed in polymetallic sulphides. Indium recovery is based primarily on zinc extraction from sphalerite, the prototype of so-called tetrahedral sulphides, wherein metal ions fill half of the available tetrahedral sites within the cubic closest...

The purpose of this study is to analyze the quality optical properties such as energy band gap thin layer tin oxide doped with aluminum, fluorine, indium, aluminum-fluorine, aluminum-indium, and aluminum-fluorine-indium. was synthesized using sol-gel spin coating method. ratio basic ingredients doping used in 95:5% 85:15%. that has been formed then heated at a temperature 100 200 0C. results an...

Colloidal quantum dots (QDs) exhibit highly desirable sizeand shapedependent properties for applications from electronic devices to imaging. Indium phosphide QDs have emerged as a primary candidate to more toxic CdSe QDs, but production of InP QDs with the desired properties lags behind other QD materials due to a poor understanding of how to tune the growth process. Using high-temperature ab i...
