Özet

Bacterial synthesis of nanoparticles (NPs) is a green chemistry approach that interconnects nanotechnology and microbial biotechnology. Some types of bacteria are used for the production of these NPs. In this study, CuSe-NPs and ZnSe-NPs have been synthesized by using selected special bacterium under dark conditions and characterized by Transmission electron microscopy (TEM). The solutions of synthesized CuSe-NPs and ZnSe-NPs were distributed dropping on the glass and p-Si substrates separately and then they were dried at 65 degrees C. Optical properties of the ZnSe and CuSe thin films formed on glass substrates have been investigated by ultraviolet-visible spectrophotometer (UV-VIS). Structural, morphology, and chemical compositions of the fabricated ZnSe/p-Si and CuSe/p-Si structures have been determined by X-ray diffraction (XRD) and Field-emission scanning electron microscopy (FE-SEM) with energy dispersive X-ray spectroscopy (EDS) techniques, respectively. In addition, some electrical parameters of Au/ZnSe/p-Si/Al and Au/CuSe/p-Si/Al structures have been found by current-voltage (I-V) measurements at room temperature and the obtained results have been compared.
