Caracterización De Nano Materiales De Cdse, Cdte Y Cd0.5mn0.5te Formados Por Ciclos De Presión
Resumen del Libro
This research propose the formation and structural and morphologic characterization of nanoparticles semiconductors of CdSe, CdTe and Cd0.5Mn0.5Te, from your solid phase mono crystal in bulk, for the cycles of pressure applications to T=300K (way Top Down). The maximum pressures applied are under of 11GPa, using the cell of great volume type Paris-Edinburgh. The sample recovers were characterized using diffraction of X-rays, electronic microscopic of transmission, diffraction electrons and Raman dispersion, and it achieve to determine that they are spherical nanoparticles with average diameter lower 50nm. With the SQUID Magnetometer and magnetization in the High Magnetic Field Pulsed, we determined the behavior of the nanoparticles of Cd0.5Mn0.5Te to low temperatures and this is guided by ferromagnetic contribution of the spin of surface, that put on top on behavior of spin glass.
