Abstract In modern information technology, charge-based logic is realized in semiconductor micro-processors, while ferromagnetic metals enable the use of carrier spin and associated magnetic moments for information storage. However, this is only the tip of the iceberg. The control of spin and magnetism in a wide class of materials and their nanostructures, generally referred to as spintronics has the potential for a much broader impact. In this proposed work I will explore a new generation of multifunctional devices that seamlessly integrate memory and logic for low-power/high-speed operation and open new avenues for transferring information. However, before this integration can be realized, a deeper understanding is required of how spin and magnetism can be tailored in semiconductors and their nanostructures. In this proposal, I am applying for a scholarship award to initiate several new research directions in Brazil which will be made possible by my sabbatical visit to the group of Prof. Igor Zutic at the University at Buffalo, the State University of New York, USA. Prof. Zutic is a renowned expert in the fields of spintronics, spin transport and magnetism with important works in his own area and also several important reviews and a recently co-edited book in the field. The goal of this stay is to establish a strong collaborative research focusing mostly on spin and magnetism in semiconductors, by combining my expertise in electronic structure calculations with the one available in the group of Prof. Zutic at Buffalo. The subjects to be studied are: silicon spintronics, spin lasers and magnetic quantum dos; always combining electronic structure and transport and magnetic properties, aiming the understanding of basic spin and magnetic properties and the analysis and proposals of new spintronic devices. This effort will also be strongly enhanced by my close collaboration with several experimental groups at Buffalo who are working on various spin-dependent properties of semiconductors and their nanostructures.
