Helmholtz Young Investigators' Group at HZDR, Dr. S. Zhou, Ion beam processed functional materials for spintronics and photovoltaics
The Helmholtz Young Investigators' Group (funded since March 2011) is led by Dr. Shengqiang Zhou. The research focus is “ion beam processed functional materials for spintronics and photovoltaics”. Ion implantation plus pulsed laser annealing offer a unique, non-equilibrium approach to design highly doped semiconductors, which are key materials for semiconductor spintronics and the new generation of solar cells with a conceptual innovation. We are addressing the following scientific issues:
- The melting and solidification process of ion implanted semiconductors upon laser irradiation;
- Using ion implantation and short time annealing to fabricate highly doped semiconductors for spintronic and photovoltaic applications;
- The defect engineering of diluted magnetic semiconductors by ions: finely tuning the carrier concentration and creating planar local structures;
- Improve the homogeneity of photovoltaic thin films using short-time annealing;
- Using ion beams to better understand highly doped semiconductors: lattice location of impurities, depth profile of impurity concentration and strain.
Using ions we can do many things for semiconductors, the work horses for modern information technologies.
