Approches numériques du transport de charges dans les semiconducteurs organiques

Using plastics or dyes like molecular semiconductors to make optoelectronic devices at low cost is a project in industry that is of great interest to the "Information Community" of this beginning of the 21st century. Some applications of this technology ha ...

Polarization effects in the channel of an organic field-effect transistor

Libero Zuppiroli, Marie-Noëlle Bussac, Jean-David Picon, Hocine Houili

We present the results of our calculation of the effects of dynamical coupling of a charge carrier to the electronic polarization and the field-induced lattice displacements at the gate interface of an organic field-effect transistor (OFET). We find that t ...

Charge transport across organic-organic interfaces in organic light-emitting diodes

Libero Zuppiroli, Eduard Tutis, Hocine Houili

The process of hopping transport across organic heterojunctions is critical to the function of organic light-emitting diodes (OLED) and many other currently developed organic electronic devices. We consider the case of a hole-only or homopolar heterojuncti ...

Investigation of the charge transport through disordered organic molecular heterojunctions

Libero Zuppiroli, Eduard Tutis, Hocine Houili

We present a three-dimensional multiparticle Monte Carlo (3DMPMC) simulation of hopping transport in disordered organic molecular media. We used this approach in order to study the charge transport across an energetically disordered organic molecular heter ...

Insights into OLED functioning through coordinated experimental measurements and numerical model simulations

Libero Zuppiroli, Detlef Berner, Hocine Houili

We present some typical applications of our device simulation model "MOLED" which has proven to be a very useful tool for obtaining insight into the functioning of multi-layer organic light-emitting devices (OLED's). Our general approach consists of combin ...
