Nanostructures for Single Photon Emitters

Dear Colleagues,

The goal of achieving stable and reliable non-classical photon sources might be useful for different research fields, such as metrology or quantum communication, and is demanding in several quantum computation schemes.

Quantum technologies would greatly benefit from a standard technology for single photon sources and many promising systems have been developed in the last years. In this framework, solid state single photon emitters (SS-SPE) play a key role, due to their scalability and easiness of integration in photonic devices. Diverse types of SS-SPE have been proposed in literature, from atomic defects in crystalline structures to quantum dots and 2D materials, just to mention some of them. Unfortunately, for most of the mentioned systems the performances are typically limited in terms of collection efficiency and decay rate.

The increasing ability to fabricate structures at the nanoscale by more and more accurate lithographic and material growth techniques have opened the opportunity to tailor the photonic environment surrounding an emitter to engineer its emissive properties, in terms of radiation pattern, as well as decay rate.

The Special Issue of the journal of Applied Science “Nanostructures for Single Photon Emitters” aims to provide an overview on recent advances in the development of SS-SPE and the improvements of their performances.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Applied Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
