Iron oxide nanoparticles (NPs) of 8nm have been infiltrated into the pores of porous silicon. The aim is to create a superparamagnetic (SPM) nanocomposite system with maximized magnetic moment. Therefore the particle–particle distance versus the superparamagnetic behavior has been figured out. The blocking temperature T B which indicates the transition between SPM behavior and blocked state...
A semiconductor/metal nanocomposite is composed of a porosified silicon wafer and embedded ferromagnetic nanostructures. The obtained hybrid system possesses the electronic properties of silicon together with the magnetic properties of the incorporated ferromagnetic metal. On the one hand, a transition metal is electrochemically deposited from a metal salt solution into the nanostructured silicon...
The presented hybrid material consists of a porous silicon matrix and precipitated metal nanostructures within the pores. The porous silicon is achieved by wet etching of a silicon wafer, offering straight pores grown perpendicular to the surface. Ferromagnetic metals are electrochemically deposited within the pores leading to a composite material merging the electronic properties of silicon and the...
