Abstract
Recent evidence suggests that the need for employing a new characteristic with low-cost preparation tools and high performance for applications. These properties have been achieved by using a high stable 2-aminoanthracene-9,10- dione thin films (AAD), prepared by thermal evaporation technique under a vacuum of 10(-5) Torr. The surface of the films was checked by SEM for studying the RMS-roughness characteristics and grain - boundary influence. Added to this study, the crystalline performance was also considered as the main requirement for identifying the main crystal parameters. Most important results were focused on TGA results for confirming the thermal stability through the chosen measurements. The investigation of the spectral dependence of the absorption of the AAD films specifies the occurrence of high probability for indirect transition as compared to the direct allowed with energy gaps of 1.55 and 2.28 eV. The dispersion energy and oscillator energy, as well as most parameters, were computed using the well-known Wimple-DiDomenico formula under consideration of the single oscillator model. The spectral dependence of the linear and nonlinear controlling parameters were studied for subscription the prospect applications in photodetectors.
