Programma dettagliato e risultati di apprendimento attesi

Organic semiconductors are both a subject of advanced research worldwide and have already shown to offer interesting opportunities in the realization of new products of high innovative content.


The interest in organic semiconductors stems not only from their intriguing optoelectronic properties –which can be chemically tailored- but also from their chemical and physical peculiarities, such as the mechanical flexibility, solubility, processability at almost room temperature and on virtually arbitrary substrates, compatibility with large area coverage. Most notably, thanks to the solution processability, organic semiconductors can be processed as functional inks and dispensed by means of techniques adapted from the graphic arts, such as flexography, gravure, screen-, aersol- and inkjet- printing. All these features offer a stimulating environment for applications that can be hardly addressed by means of conventional inorganic semiconductors (large-area imagers and displays, thin-film sensors, flexible optoelectronics systems, biocompatible/disposable electronics).


The course aims at providing the scientific and technological background of this emerging field. The state of the art concerning both research findings and industrial realizations will be presented, as detailed in the following.

The course will firstly illustrate the chemistry of organic semiconductors (hints to their synthesis, chemical tailoring, structure-property relationships), and their physical and electronic properties, such as charge carrier (photo-)generation and transport, charge carrier injection, excited states, thermoelectric properties (8 hours). Then the working principles and architectures of organic devices, such as (light-emitting) diodes, thin film transistors, photodetectors, memories, photovoltaic cells, thermoelectric elements, lasers will be illustrated (8 hours). Technologies for device fabrication, with emphasis on scalable techniques (such as those adapted from graphical arts such as screen printing, inkjet printing, flexography, gravure etc.), will be presented and compared; issues and solutions related to device lifetime will be discussed (2 hours). Then the course will address advanced applications of organic electronics: digital and analog circuits, optoelectronic systems, detection of ionizing radiation, interaction with biological specimens (5 hours). A worldwide overview of industrial players, of available and forthcoming products and/or technologies will be given as well (2 hours).

The course will give to the participants a critical assessment of the development so far, of actual bottlenecks and future opportunities for organic and printed electronics.


Note Sulla Modalità di valutazione
