Thank you for submitting your manuscript "Post-growth designing the ideal quantum well structures through defect engineering" to Nature Materials, which we regret we are unable to publish.
Because there is intense competition for space within the pages of Nature Materials, we must decline a substantial proportion of manuscripts without sending them to referees, so that they may be sent elsewhere without delay. Decisions of this kind are made by the editorial staff when it appears that papers are unlikely to succeed in the competition for limited space.
Among the considerations that arise at this stage are a manuscript's probable interest to a general materials research readership, the pressure on space in the various sub-disciplines of materials research covered by Nature Materials and the likelihood that the manuscript would seem of great topical interest to those working in the same or related areas of materials research.
And I am sorry to have to say that we must take this view in the present case. We certainly recognize that this is an interesting work and we agree that your demonstration of a quantum well in SiC generated by the electron beam induction of stacking faults deserves rapid publication in some venue. However, although we feel sure that your results will be of interest and value for other specialists, I regret to say that we cannot conclude that the manuscript provides the sort of fundamental advance in general understanding or technological capability that would be likely to excite the immediate interest of a wide audience of materials scientists. Therefore, we feel that the paper would find a better outlet in a more specialized journal, rather than Nature Materials.
We are sorry that we could not be more positive on this occasion, but we thank you for your interest in the journal. Please note that our decision does not reflect any doubts about the quality of the work reported, and I hope you will rapidly receive a more favourable response elsewhere.
