The objective of the DIODE network is the optimization of a specific device, an inorganic/organic Schottky diode. This includes a detailed understanding of the inorganic semiconductor surface passivation, the subsequent epitaxial deposition of the organic layer, and finally the metallization of the organic film.

The substrate used will be GaAs, and initially, the well studied molecular semiconductor PTCDA will be used for the organic interlayer. After an optimization of the resulting GaAs/PTCDA/metal high frequency Schottky diode, alternative organic materials will be evaluated.

Training Programme

The DIODE network provides a unique training environment for young researchers due to the combination of high quality theoretical, experimental and technological centres. While concentrating on acquiring specific expertise at the host institution, the young researchers will gain an appreciation of the entire process from fundamental scientific research to commercial device manufacture. In addition to conventional collaborative work, short dedicated training sessions will be provided where expertise available at one centre helps to advance progress at a partner institution. A key part of the training is the communication of ideas and results. This will be realised through a programme of scheduled work shops and extensive use of internet-based techniques. Some workshops will provide a discussion forum for young researchers and others will provide training in project management and skills. The DIODE network has already established a dedicated web page and will make use of video conferencing. This training package will equip the young researchers for careers in both the academic presentation and the industrial sectors at the opening of a new chapter in semiconductor science and technology.

The three companies, FCM, SynTec, and UMS, are potential employers for the young researchers in the DIODE network. They cover a broad industrial area from GaAs wafer and organic molecule fabrication to GaAs diode application. The close links established between them and the DIODE network and in particular their participation in the workshops increase the opportunities for the young researchers to get in touch with industry, learn about industrial needs, and perhaps revise their careers accordingly.
