Structural and electronic implications for carrier injection into organic semiconductors

Philippe Bugnon, Mauro Castellani

We report on the structural and electronic interface formation between ITO (indium-tin-oxide) and prototypical organic small molecular semiconductors, i.e., CuPc (copper phthalocyanine) and alpha-NPD (N,N'-di(naphtalen-1-yl)-N,N'-diphenyl-benzidine). In pa ...

Controlling charge-transfer at the gate interface of organic field-effect transistors

Libero Zuppiroli, Adrian von Mühlenen, Mauro Castellani

The performance and charge transport characteristics of pentacene transistors with oxide gates such as SiO2 and Al2O3 have been recently shown to largely depend on the density of residual carriers due to electron acceptor defects at the oxide surface. The ...

Competition between excitons and exciplexes: Experiments on multilayered organic light emitting diodes

Detlef Berner, Mauro Castellani

The electronic processes responsible for charge transport and electroluminescence in multilayered organic light emitting diodes (OLEDs) are very sensitive to the properties of the organic heterojunction. In particular, the height of the energy barrier affe ...

Efficient blue light-emitting diodes based on a classical "push-pull" architecture molecule 4,4 prime -di-(2-(2,5- dimethoxyphenyl)ethenyl)-2,2 prime -bipyridine

Philippe Bugnon, Michael Graetzel, Mohammad Khaja Nazeeruddin, Libero Zuppiroli, Rosario Scopelliti, Detlef Berner, Mauro Castellani, Filippo de Angelis

A novel, highly blue luminescent molecule containing donor and acceptor groups, 4,4 prime -di-(2-(2,5-dimethoxyphenyl)ethenyl)-2,2 prime -bipyridine, that shows photoluminescence emission at 450 nm with 43% quantum yield is designed and synthesized. Time d ...

Interface issues in organic semiconductor based devices

Mauro Castellani

The present doctoral thesis aims to contribute to the field of organic semiconductor physics and technology, both of which have become fast growing disciplines. Two technological applications are emerging from these research efforts: Organic light-emitting ...
