Structural and optical characterization of CdTe quantum dots thin films

Sigmoid-growth curve of lattice-constant against annealing-temperature of Cd1−xZnxTe thin films and its structural, optical and morphological characteristics

“…The relative absence of charge-impurities or defects had also prompted increase in band-gap of T 6 -T 7 . The increased band-gap in T 6 and T 7 could also be attributed to decreased particle size [25] as was latter reconfirmed from SEM micrograph. …”

STRUCTURAL AND OPTICAL PROPERTIES OF CdTe THIN FILMS OBTAINED BY ELECTRODEPOSITION

“…In Figure 1, one can determine the size of the grains D on CdTe thin films, which are as-deposited and thermally treated at different temperatures (Table 1). Depending on the height and width of the highest peak, the average size of the grains is determined and it is calculated using the Debye-Scherer relation [26]:…”

Effect of annealing on the structural properties of thermal evaporated CdIn2Te4/CdS thin film solar cells

“…where D is the crystal size, is the wavelength of the X-ray source, ␤ is half the maximum width of the diffraction peak in radians, Â is the Bragg angle XRD diffraction peak, and k is a constant related to the film whose particle size was calculated [34]. Using the XRD profile, the inter-planar distance (d) and lattice constant (a) can be calculated according to Bragg 's law [19]:…”
