Special Issue Information
Dear Colleagues,
One of the most important materials recently used in optoelectronic devices, e.g., laser diodes, quantum light sources, and photodetectors, is the semiconductor nanostructure (e.g., the quantum dot, well, or superlattice). It shows excellent properties as an optical emitter or absorber and the potential for mass production. A three-dimensionally confined quantum dot shows properties that are greatly attuned by the surrounding ‘environment’, e.g., doping, the local electric or strain field, or the band structure, which is promising for symmetric exciton or higher-order exciton formation, less dephasing or fast-decay emissions, and a high-sensitivity detection. With a quantum emitter, one of the major challenges is to build symmetric exciton with less barrier scattering and align the quantum dot to a nano-cavity (or static field) for optimal enhancement (or electric tuning). This can be achieved by optimizing the growth surface, cladding strain, junction field, epitaxial lift-off, and alignment technique.
In this Special Issue of Nanomaterials, we aim to present the current use of hybrid nanostructures in optoelectronics, a field that has blossomed since the 2000s, with seminal discoveries regarding quantum dots as single photon or laser emitters that have subsequently been developed further. For this Special Issue, we invite contributions from leading groups in the field, with the aim of presenting an overview of the state of the art in this discipline.

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. Nanomaterials 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 2900 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.
