In spite of the fact that degradation phenomena produced in materials and devices in radiation fields, and the defects in crystalline semiconductors are studied since more than half a century, a lot of aspects are not yet clarified. The aim of the present project is to bring contributions in this subject. So, this is of fundamental research, situated at the border between semiconductor physics, particle physics, atomic and nuclear physics, with potential to be applied in high energy physics, in the information technology, in nuclear medicine.
The problems related to the correlation of defect production with the energy deposited in crystalline semiconductors in radiation fields and with spatial distribution of produced defects, to the interactions between primary defects and of their aggregation in stable defects (clusters), the stability and metastability of these agregates using energetic and thermodynamic considerations will be studied
In this project, both theoretical and experimental methods will be used.
The aim and the objectives of the project are in the frame of the programme IDEI from PNCDI II, and also in the top research subjects of the international scientific community. The research team is composed from the principal investigator, who works in the field since 1990, from two experienced researchers, one specialised in semiconductor physics (mainly electric measurements and modelling), the other (postdoc) specialised in theoretical physics, and from 3 early stage researchers: one PhD student and other 2 which could enrol in PhD studies during the project. The dissemination of results will be performed in the web page of the project, in 4 publications in ISI quoted journals, in 3 communications in international conferences, in the research and auto-evaluation reports
