Influence of composition on optical and dispersion parameters of thermally evaporated non-crystalline Cd50S50−xSex thin films

Study of optical properties of thermally evaporated ZnSe thin films annealed at different pulsed laser powers

“…It has a Ni-filter and provides a angles were ranged from 4 o to 90 o . These operating parameters allowed to proper examine the samples and detect all possible diffraction peaks [17,26].…”

“…This model has an advantage in fitting the experimental data because it provides an intuitive physical interpretation of the measured quantities [17]. the difference between E o and E g , yet there is an approximate empirical equation…”

“…where β is a constant whose value depends on the chemical bonding character of ZnSe thin film sample, which was listed in Table 2 M A N U S C R I P T following equation [17,39]:…”

“…The calculated values of n(0) and ஶ were also listed in Table 2 ε ∞ = and the ratio N/m* by the following equation [17,32]:…”

“…This blue shift can be interpreted in terms of the increase of the particle size and the structural changes which occurred in the films such as growth of nanocrystallites into larger crystallites [8,17,45]. …”
