   Group Conductive and superconductive [ More details ]

Person in charge: Samia Kaddour
The searches for this group relate to the study of the drivers and superconductors. Several studies were undertaken on various superconductors’ energy of the organic superconductors to the superconductors at high critical temperature via the superconductors containing carbon like the fullerenes and the nanotubes of carbon. We developed ideal models to interpret and explain various aspects of supraconductivity and magnetism or normal state of these materials. These research tasks were the fruit of collaborations with teams of experimenters.
PROSPECTS
The team “drivers and superconductors” has the ambition to form a core of researchers in the field of the superconductors and the strongly correlated electrons able to develop ideal models to answer the challenges of modern physics. The group is interested particularly in the materials which have a promising future on the level of the technological applications and in the field of the nanotechnology.

   Group optical properties and electronic transport in nanostructures of semiconductors [ More details ]

Person in charge: Sihem Jaziri
Born from the miniaturization, the quantum boxes are built starting from a two-dimensional structure and the record of side dimensions is not lower than 300 Å. What is certainly not the last mot. It is with this class of broad boxes than we are particularly interested. We developed a model of calculation of the binding energy of the exciton for quantum wells of intermediate widths. This model is primarily based on the separate containment of the charge carriers. The main aim of this preliminary calculation is to show that this separation of quantification of the electron and the hole is badly adapted for the problem of transition between confined systems.

   Group of Growth and Characterizations Multi-scales of Materials Semiconductors Used in the Photovoltaic Devices [ More details ]

Person in charge: Najoua Kamoun

By using two simple techniques of growth the CBD and the spray which are inexpensive techniques, allowing to obtain large surfaces and whose results are promising, we approached the realization of the solar cells:

SnO 2 /In 2 S 3 /CuInS 2 /Au, SnO 2 /ZnO/CuInS 2 /Au, SnO 2 /ZnS/CuInS 2 /Au

SnO 2 /In 2-x Al x S 3 /CuIn 1-x Al x S 2 /Au, SnO 2 /ZnO/CuIn 1-x Al x S 2 /Au, SnO 2 /ZnS/CuIn 1-x Al x S 2 /Au, SnO 2 /SnxSy/CuInS 2 /Au et SnO 2 /Sn x S y /CuIn 1-x Al x S 2 /Au

PROSPECTS
On a macroscopic scale, the semi-conductives layers carried out are characterized by techniques of crystallographic analysis (X-rays), Chemical (Spectroscopy of electrons Auger, electronic Sonde), optics (Ellipsometry, Transmission, Reflexion) and electric (Vibrating capacitor).
On the scale microphone-nanoscopique, we will record their morphology (MEB, AFM), their cartographies optics (SNOM) and electric (EFM), in order to study the role of crystallites and of unite grain. We will study the adhesion of the layers and their structure by acoustic Microscopie.
We will be interested under investigation of the interfaces between the various layers constituting the device (optical Window, layers activate, absorbing, conducting, plug).
Measurements of output, of spectral sensitivity will be taken on the finished device.
Repercussions in the field of the nanosciences are required through the study of the Nanocrystals one.
Contracts with the industrialists will be required in order to produce solar cells at weak cost and using these devices of conversion of solar energy into electrical energy to thereafter reduce the cost of energy utilization by the Tunisian citizen and can be foreign or with the international scales.

   Group Simulation and Modeling [ More details ]

Person in charge: Raouf Bennaceur

Within the framework of this work we chose, in a first phase a natural radiation source: the “cosmic radiation”. This radiation consists of neutrons, protons in great proportion and other particles.

PROSPECTS
It is a question of developing a competence in the field of simulation and the modeling in order to interpret the phenomena physique to observe and of as well envisaging interesting applications in the field of energy as in the field of the TIC.
