ABSTRACT.......

At the forefront of the current scientific revolution of nanoscience nanocrystals (NCs), crystalline particles grown in liquid media, stand out over other classes of inorganic nanomaterials due to the high degree of control with which their crystal structure, size, shape, and surface functionalities can be engineered in the synthesis stage and to the versatility with which they can be processed and implemented into a large spectrum of devices and…

ABSTRACT...

Manipulation of carrier spins in semiconductors for spintronics applications has received great attention driven by improved functionalities and higher speed operation. Doping of semiconductor nanocrystals by transition-metal ions pronounced as diluted magnetic semiconductors (DMS) has attracted tremendous attention. Such doping is, however, difficult to achieve in low-dimensional strongly quantum-confined nanostructures by conventional growth procedures.…

Despite a long history of success in the synthesis, the origin of magnetism in diluted magnetic semiconductors (DMSs) is yet a controversial issue. Doping, that is, intentional incorporation of impurities into a material, is the crucial means of alteration the electronic, optical and magnetic properties of semiconductors. Cr-based DMSs go halves with the other due to remarkable magnetic and magneto-optic properties, originating from the "sp-d" exchange interaction…

Doping, that is, intentional incorporation of impurities into a material, is the crucial means of alteration the electronic, optical and magnetic properties of semiconductors. Cr-based DMSs go halves with the other due to remarkable magnetic and magneto-optic properties, originating from the "sp-d" exchange interaction flanked by the band…
