Publication: Time-resolved cathodoluminescence microscopy with sub-nanosecond beam blanking for direct evaluation of the Local Density of States. Link to the publication.
What is your publication about:
The processes that lead to emission of light by molecules or other solid materials are typically studied using pulsed lasers in an optical microscope. However, with an optical microscope, details smaller than the wavelength of the light cannot be resolved. With electron microscopes a very high resolution can be achieved. We describe a method to generate very short electron pulses, with a duration comparable to pulses from diode lasers, inside an scanning electron microscope. We also show that the pulsed electron beam can then be used to study light emission with a resolution that is ten times better than that of optical microscopes.
How did the Open Access fund support you in that process:
The project in which these results were obtained was already formally closed, so we could not use any project money anymore to support this publication. Thanks to the OA Fund, this work could still be published in an open access journal.
How did you know about the fund:
I previously published journal papers via the OA Fund.
Are you familiar with the governmental goals and the TU Delft policy concerning Open Access?
Yes, I was one of the advisors on the Open Science policy of TU Delft on behalf of my faculty.
What is your view on Open Access publishing?
It is important that scientific articles are available to everyone. This accelerates scientific progress in general and it also means that your work can in principle reach a larger audience and thus higher chance it reaches the people to whom it can be useful. Students, scholars but also scientists and others should have free access to available knowledge no matter where they are. Now that everyone accesses the works online, it is a strange situation that the amount of resources you can access, as a student or as a scientist, depends on the money your university can spend on institutional journal licenses. Especially since these fees still originate from a time where everything needed to be published in print.
What are your plans for the future:
We just submitted another study on this subject, also to a journal that supports open access publication. A paper on a different subject, also supported by the OA Fund, should come out soon. We send back our proof corrections just yesterday. And two papers with external collaborators are currently under review at open access journals. I hope many more will follow in the near future.
