Abstract

The aim of this project is the development of fundamental research at the frontier of low-dimensional systems sciences. The scope of the Project embraces nanostructures in general, with a special focus on semiconductor systems. The majority of the projects proposed here follows the on-going research of the main researchers of the working team of this project. Furthermore, there is also a strong effort in the direction of more diversification toward new nanostructural materials involving a more multidisciplinary research. The main strategy of the team is a strong collaboration between theoretical and experimental researchers. We also envisage an increase in the interchange with other laboratories in Brazil and outside the country. We emphasize the strong link with the Optoelectronic Group of the National Laboratory of Synchrotron Light (LNLS), particularly in relation to the research involving the growth of new semiconductor materials. The participation in this project of the Theory Group of the LNLS, which is starting its activities, will be of great importance to strengthen this collaboration. Shortly, the aims of this Project are: to contribute to the formation of experimentally and theoretically highly skilled personal, with a strong experience in group work. This will cover all levels, from undergraduate students up to pos-doctoral researchers. We understand that all levels of education must be considered in a self-contained way, considering the different levels of professional activities that can be contemplated; to develop scientific and technological expertise at international standarts with an effort to significantly contribute in some areas of specific knowledgement; to investigate new physical effects, to explore the dimensionality of the semiconductors as well as new nanostructures systems and their integration with other materials; to offer a scientific support to other experimental groups in the Country, with emphasis in the integration among experimental and theoretical groups. The projects to be developed will keep the policy started in 1992, that is: free access to all laboratories and the computational facilities in a cooperative way by all members of the team. The team already has laboratories of excellent quality to investigate optical properties and we look forward to improve these facilities. We also envisage to strengthen the collaboration with the LNLS, in particular in the fabrication and processing of new materials as well as the investigation of transport properties. This collaboration will be favored with the participation of the Theory Group which is being created at the LNLS. The description of the existing equipment and the computational facilities are detailed in this project and we describe and justify the equipment we are applying for in order to improve the existing facilities and to develop the Theory Group at the LNLS. We also contemplate the collaboration with other crystal growth groups in Brazil and outside the Country... (AU)
