International Conference on
Semiconductors that exhibit room-temperature
ferromagnetism are central to find ways to manipulate
and use electronic spin to the same degree that electronic
charge is used in silicon-based electronics. Diluted magnetic
semiconductors (DMS) are a promising class of such materials
to the development of semiconductor spintronics, but their
success will depend on our ability to understand and optimize
their behavior. The interface between first principle and
experimental materials design could provide a way to achieve
these goals. The purpose of talk is to propose some ideas to
answer the most important question in material science for
semiconductor spintronics, namely, how we can realize room-
temperature ferromagnetism in DMS? And I will discuss the
correlation between first principle and experimental design to
see how we can predict the properties of yet-to-be-synthesized
materials. Based on experimental design I will discuss structural
andmagnetic properties of same DMSmaterials. Based on first-
principles spin-density functional calculations, the half-metallic
ferromagnetic properties of same DMSmaterials withmagnetic
impurity have been investigated. New magnetic behaviors will
be discussed in DMSs recently observed as spin glass, super
paramagnetic, this creates new opportunities for development
and construction a new spintronics devises.
Speaker Biography
Dr. Omar Mounkachi is a researcher and project leader in the Moroccan Foundation
for Advanced Science, Innovation and Research (MAScIR). He has obtained his Ph.D
at University Mohammed V in collaboration with NEEL Institute (CNRS, Grenoble)
in 2009. Dr. Mounkachi has more than 8 years’ experience in performing and
managing research within several international academic collaboration (France (CEA
Grenoble (2008/2009), laue langevin institute (2010/2012)) , university of Strasbourg
(2015/2016) , and the jean lamour institute (2014/2016), Poland (Polish Academy
of Sciences ( 2009)), Belgium (University of Liège (2015/2016), USA (university of
central florida, wake forest university (2009/2016)) and industrials cooperation
(MANAGEM,OCP,PEPS,ECOMAG, SOLVAY, McPhy ) . He has published 100 publications
in highly recognised scientific journals in several fields of condensed matter,
spintronics, energy, and magnetic nanomaterials, and 16 patents. He is co-organizer of
several national and international conferences. Dr. Mounkachi has been invited to give
seminars in many congresses and to act as a reviewer for many scientific manuscripts
from prestigious journals.
