Scanning Tunneling Luminescence of Pentacene Nanocrystals

Alexander Kabakchiev

Organic semiconductors are promising materials for future electronic and electroluminescence applications. A detailed understanding of organic layers and nano-sized crystals down to single molecules can address fundamental questions of contacting organic s ...

New Approaches towards Organic Photodetection and Bio-Integration

Diego Ghezzi

Organic semiconductors technology has only recently started to merge with biology and medicine, especially in the field of polymeric coatings as protective layers for artificial devices. Very few examples, however, report the use of semiconducting polymers ...

Magnetic field effects on the conductivity of organic bipolar and unipolar devices at room temperature

Frank Nüesch, Libero Zuppiroli

Magnetic field effects on the conductivity of different types of organic devices: undoped and dye doped aluminium (III) 8-hydroxyquinoline (Alq3)-based organic light emitting diodes (OLEDs), electrononly Alq3-based diodes, and a hole-only N,N'-diphenyl-N,N ...

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 ...

Enhanced hole injection in a hybrid organic-inorganic light-emitting diode

Michael Graetzel

The operating mechanism, particularly the carrier injection mechanism, of a hybrid organic-inorganic light-emitting diode (HOILED) is reported. Asymmetric hole injection has been observed in a symmetric hole-only device, which has two identical interfaces ...

Sublimation Not an Innocent Technique: A Case of Bis-Cyclometalated Iridium Emitter for OLED

Michael Graetzel, Mohammad Khaja Nazeeruddin, Rosario Scopelliti, Libero Zuppiroli, Philippe Bugnon, Stéphane Suarez

Isomerization of a neutral bis-cyclometalated iridium(III) complex has been observed for the first time during the preparation of vacuum-processed organic light-emitting devices (OLEDs) and reproduced in solution. Isolation of the isomer revealed a cis org ...

2008

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 ...

EPFL2006

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 ...

EPFL2006

We have used electrically detected magnetic resonance (EDMR) to study a series of multilayer organic devices based on aluminum (III) 8-hydroxyquinoline (Alq3). These devices were designed to identify the microscopic origin of different spin-depe ...
