For nearly a year now, my research collaborators and myself have been trying to publish a paper which, amongst other things, describes a new method for determining the energy required to dope materials. particularly but not exclusively for optical applications. We’ve submitted to IOP’s Journal of Physics: Condensed Matter, that we have published in extensively over the past 15 years. They have just rejected this work for a third time without giving any explanation except that they don’t think the paper contains ‘new science’ (on which we clearly disagree!) Of course there are other journals, and our paper will get published eventually, but this has proved to be an immensely frustrating experience.
