Raman Spectra Of Cdte Thin Films Grown By Pld Spectra Show The A 1 And Fig. 4 shows the raman spectra of cdte films grown by pld at different substrate temperatures. all spectra showed the long itudinal optical (lo) mode at a frequency of 166.5 cm À 1. This study presents the fabrication and characterization of cadmium telluride (cdte) thin film, for solar cell applications. the technique used for the deposition part was pulsed laser.

Raman Spectra Of Cdte Thin Films Grown By Pld Spectra Show The A 1 And Fig. 4 shows the raman spectra of cdte films grown by pld at different substrate temperatures. all spectra showed the longitudinal optical (lo) mode at a frequency of 166.5 cm −1 and their second order mode (2lo) at 333 cm −1, characteristic of cdte [3]. The films, annealed in air at 400 °c, exhibited a cubic structure with near stoichiometric composition (cd te ≈ 1.1) and a grain size of ~ 1 µm. temperature dependent study analyzed the shifts and broadening of to, lo, and 2lo phonon modes. In the present work, the results of optical absorption, xrd, and raman analyses are combined in order to study the effect of particle size evolution, thickness dependent strain, and structural disorder. In this work, we have studied the influence of rf power on structural and optical properties of cdte thin films deposited by indigenously designed locally fabricated rf magnetron sputtering.

Cdte thin film was deposited on substrate glass using pld set up (figure 1) based on an nd:yag laser with a wavelength of 1064 nm, a repetition rate of 6 hz, and a pulse laser duration of 9 ns. In this report, both the so and the bulk raman scattering efficiency were dramatically enhanced in cdte thin films by employing silver nano plasmonic enhanced raman scattering and maximized free surface atomic vibration. Abstract: polycrystalline films of cds, cdte, as well as cds cdte heterojunctions grown by rf magnetron sputtering and by pulsed laser physical vapor deposition are studied using the techniques of sem, photoluminescence (pl), and raman scattering. This study focuses on the evolution of material properties as a function of the applied potential and the film thickness, demonstrating the possibility to obtain a new te rich compound with a ii vi ratio of 1 2 under specific bath conditions.
