ABSTRACT

In this paper, we have interest in the CdSe (cadmium selenide) semiconductor due to their physical and optical properties that depend on their morphology and size, as well as their possible applications in electronic and optoelectronic fields, for example, in the fabrication of solar cells or nanotransistors. For this reason, we synthetized nanoparticles of CdSe using the colloidal method, and varied the pH value: 8 to 12, to know the effect of pH on the samples. The nanoparticles were characterized using the SEM (scanning electron microscope) and STM (scanning tunneling microscope) to know the morphology and electronic cloud on the surface of the samples. In each case, we found different sizes (from 6 to 11.5 nm) and shapes as filaments (fibbers), bars and spheres of CdSe nanoparticles and the 3D-FFT was obtained too.

KEYWORDS
