The envisaged research involves a multidisciplinary field comprising organic chemistry, physical chemistry, chemical engineering, and condensed matter physics. My main interest is focused on the synthesis and the self-assembly of well-defined organic molecules having sufficient optical and electrical properties that allow them to be used as valuable materials for optical and electrical devices.

In addition, we are highly interested in studying both self-assembly as well as the charge transport phenomenon of such organic molecules.

Organic Field Effect Transistors

Organic Thin Film Transistors (OTFT) have became of great interest to fabricate a low cost, and large area electronics that donít require a high resolution and complex fabrication processes and whose performance/cost ratio is acceptable to be used in many applications as price tags, flexible computer screens and cell phones.

Self-assembly by Pi-Stacking

Large disc-shaped aromatic molecules self-assemble by Pi-overlapping forming long columnar nanostructures. We focus on the electronic transport of such compounds which are promising candidates as nanowires.

Nanotechnology, a research area that covers many scientific disciplines such as Medicine, Biology, Physics and Chemistry has found a great interest in research institutions and wide applications in industries. This is due to many reasons; from those we note the control down to the molecular level providing, thereby, a greatest efficiency and an important benefit as a reason of the low cost of the fabricated molecules and devices.
