Special Issue Information
Dear Colleagues,
Colloidal quantum dots represent a promising class of solution processible semiconductors with a wide range of applications ranging from light harvesting and light emission to lasing and photocatalysis. The choices of the semiconductor core, sizes, defects, ligands that bind to the surface, and the arrangements in thin film devices allow quantum dots properties to be highly tunable. Quantum dots have also found commercial success in display technology, spurring further research into improving their synthesis and manufacturing processes. More recently, efforts have focused on reducing toxicity in these materials, such as using lead-free and cadmium-free alternatives. Additional functionalities have been endowed onto quantum dots—for example, through the doping of the semiconductor core with magnetic elements or chiral ligands for application in spintronics, or the passivation of quantum dot surface with specific organic molecules for harvesting triplet states. These experimental advances have also been accompanied by our increased understanding of the underlying physical processes, such as exciton transport, self-trapped exciton, and defect physics. First-principles calculations, ultrafast spectroscopy, and advanced imaging techniques have allowed us to probe the electronic and optical properties of quantum dots at a more detailed level.

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 100 words) can be sent to the Editorial Office for announcement on this website.
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. Micromachines is an international peer-reviewed open access monthly 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 2100 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.
