Enhanced magnetic moment with cobalt dopant in SnS2 semiconductor

Imaging "invisible" dopant atoms in semiconductor nanocrystals.

Nanometer-scale semiconductors that contain a few intentionally added impurity atoms can provide new opportunities for controlling electronic properties. However, since the physics of these materials depends strongly on the exact arrangement of the impurities, or dopants, inside the structure, and many impurities of interest cannot be observed with currently available imaging techniques, new me...

Giant magnetoresistance in semiconductor / granular film heterostructures with cobalt nanoparticles

We have studied the electron transport in SiO2(Co)/GaAs and SiO2(Co)/Si heterostructures, where the SiO2(Co) structure is the granular SiO2 film with Co nanoparticles. In SiO2(Co)/GaAs heterostructures giant magnetoresistance effect is observed. The effect has positive values, is expressed, when electrons are injected from the granular film into the GaAs semiconductor, and has the temperature-p...

Synthesis and Investigation of Optical and Magnetic Properties of Co-Doped effect on Zinc Oxide Nanoparticles

In this study, the effect of simultaneous doping of magnesium, calcium, and copper ions on the properties of zinc oxide doped with cobalt was investigated. The sol-gel method has been used for the synthesis of nanoparticles. The structural and optical properties of the synthesized nanoparticles were investigated using X-ray diffraction (XRD), infrared spectroscopy (FTIR), and DRS spectroscopy. ...
