Organic OptoElectronics Laboratory

The Organic OptoElectronics Laboratory (OrgOEL) at Sincrotrone Trieste, established in 2009, investigates the properties of organic semiconductors upon funded projects in the field of organic optoelectronics.  The laboratory activities span from fundamental research in the field of electrical and optical properties of organic semiconductors to their application in devices like light emitting diodes (OLEDs), photovoltaic cells (OPVs), photodiodes (OPDs), field effect transistors (OFETs), sensors,  etc.  Activities aimed at the fabrication of ordered nanostructures by wet processing over large areas, functional to the above mentioned focus, are also carried out.
   Active collaborations are ongoing with other Elettra Beamlines (SISSI, ALOISA, SYRMEP), with italian (Dept. of Physics of the Univ. of Bologna, Dept. of Electronic Engineering of the Univ. of Cagliari) and international research groups (Center of Excellence in Microelectronics Optoelectronics and Processes-Univ. of Lisbon).  The laboratory hosts also degree and PhD students from both italian (Trieste University Graduate School of Nanotechnology) and international institutions.

Research highlights

3D transport anisotropy in organic single crystals

Three-dimensional anisotropic transport has been probed in organic semiconducting single crystals by means of both Field-Effect Transistor devices and Space-Charge Limited Current measurements.

IR studies of organic single crystals

Linearly polarized infrared studies on charge transport in semiconducting single crystals open the door for fast crystallographic assessments, and give insights into the effect of electrical polarization and charge flow on the crystal properties.
