Preface: physica status solidi (c) 7/2015

Dear participants of EuroCVD20, with pleasure we address you some words about the present conference proceedings of EuroCVD20. We faced a big challenge organizing a conference to which the full paper peer reviewed contributions will be available already with the launch of the conference! Clearly, the advantage of this procedure is the highest quality of the conference proceedings, namely peer reviewed scientific publications. Already before listening to the presentation or discussing the poster with the author, the participant of the conference will get exposed to the scientific topic, which makes him/her able to better understand the background. This opportunity opens the doors for scientific exchange with the author at its best. The educational aspects of top notch scientific discussions are based on understanding of the topics and competence in communicating the questions and answers. As time slots for oral or poster presentations at conferences are very limited the message transfer has to be well prepared between the peers, i.e. the author of the contribution and the reader of the manuscript. We are aware that some aspects speak against this procedure. The most important argument is that the latest results will not be reported in the paper. We, however, trust that none of the conference participants will be unhappy seeing latest results of a research work in the conference presentation only. Moreover, a scientifically founded discussion might even trigger optimization of the latest results and publication in a follow‐up communication. Therefore we are happy to put at disposition to all participants of the EuroCVD20 conference 49 peer reviewed full papers that have been published either in pss(a) or pss(c). We, the co‐editors of the EuroCVD20 conference proceedings, wish all readers of the collected papers insight, understanding, fun and pride. (© 2015 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
