The papers in this special issue are a selection of the keynote invited talks at the 9th European Workshop on MOVPE (Metal Organic Vapour Phase Epitaxy) held at the North East Wales Institute, Wrexham, June 10th-13th 2001. The tradition of this European Workshop series has been to have keynote invited talks with all presented papers in poster sessions to stimulate discussion on current issues in MOVPE technology and science. This selection of papers reflects some of the exciting areas of debate and a reflection on future opportunities. Indeed, MOVPE has come a long way since the first European Workshop held in Aachen in 1983. Then, the only production device using MOVPE was GaAs photocathodes, now it is a major industry dominating visible laser, IR laser and high brightness LED markets. In Wrexham, we had the largest industrial exhibition so far and reflected the changing character and growing maturity of MOVPE. So, what comes next? The first three papers in this issue cover three different approaches to obtaining 1.3 μm VCSELs. At present there is no clear winner but the goal is to obtain long wavelength emitter layers that are compatible with GaAs/AlGaAs Bragg reflectors on GaAs. The wide bandgap GaN based materials have been responsible for most of the expansion in MOVPE research over the past decade but substrates remain an issue and this is covered in the paper by M. Seyboth and M. Kamp. Another fertile topic, HBTs, is covered in the paper by F. Brunner and scope for new materials synthesized by MOVPE described by P. Wright. Finally, S. Bland gives some exciting prospects for the future shape of MOVPE technology and the challenges that are faced today to turn new research ideas into production. We hope you will find this special edition, as we do, both fascinating and stimulating as a pointer to future opportunities for MOVPE. We would like to sincerely thank all the invited speakers, the referees who helped to maintain the standards of the journal and finally Gill Rood (Southampton) and Claire Stanton and Tracey O'Connell (Kluwer) for all their help and guidance in the production of this special issue.[PUBLICATION ABSTRACT]
