X-ray Diffraction Spectroscopy Studies of CuIn2n+1S3n+2 Thin Films

Thickness dependence of structural and optical properties of cadmium iodide thin films

“…8 further shows that, the absorption edge shifts toward lower energy region with increasing film thickness. It is known that, pure CdI 2 compounds have a sharp absorption edge [12,[29][30][31].…”

Impact of Ag on the Limit of Detection towards NH3-Sensing in Spray-Coated WO3 Thin-Films

“…The introduction of Ag formed new nucleating centers for WO3, ultimately retaining monoclinic structure. The crystallite size of the films was determined by employing the Scherrer formula[19] and it varies from 11.5 nm to 14.7 nm. The dislocation density and microstrain[19] were also evaluated and are presented in Table1.…”

The dislocation density and microstrain[19] were also evaluated and are presented in Table1.Since triclinic and monoclinic phases of WO 3 exhibit the same set of XRD peaks, we have conducted Raman measurements for further confirmation[20,21].…”

Особенности фотолюминесценции и наносекундная релаксация фототока в кристаллах CuIn-=SUB=-5-=/SUB=-S-=SUB=-8-=/SUB=- при высоком уровне оптического возбуждения

“…Обладающее дефектной кристаллической структурой соединение CuIn 5 S 8 привлекает большой практический интерес в качестве сильно люминесцирующего полупроводника, фотокатода для выделения водорода из воды фотоэлектрокаталитическим методом, а также в качестве фоточувствительного элемента для изготовления высокоэффективного солнечного элемента [1][2][3][4][5][6][7][8][9][10]. Соединение CuIn 5 S 8 кристаллизуется в структуре кубической шпинели с пространственной группой O 7 h (Fd3m).…”
