Special Issue Information
Dear Colleagues,
Nano-optoelectronic materials such as epitaxial 3D semiconductor quantum dots, 2D quantum wells/superlattices, and 2D monolayers are desired for information photonics (e.g., laser diode, photodetector, saturated absorber, micro-cavity or photonic integrated circuit) and quantum photonics (e.g., single or entangled photon emitter). To achieve suitable performances from these devices (e.g., high-speed lasers with low threshold, high working temperature and monolithic wavelength, photodetectors in high detectivity, definite biexciton–exciton photon-pair emission with small fine structure splitting, or efficient nonlinear optics on chip and fiber integrated instead of bulk material), a structure regulation of these nanomaterials is needed, e.g., adding modulated doping or tunneling barrier surrounding, controlling the nanomaterial size and orientation, using a strain-reducing layer or coupled layer for longer wavelength, using biaxial strain tuning to form light hole, controlling the flux sequence to form a sharp interface, or designing proper micro-resonator modes for nonlinear optics or integrated photonics. The structure optimization and its consequent improvement of device performance can be directly reflected in the characteristics (e.g., photoluminescence (PL) or micro-PL spectroscopy, photoresponse spectroscopy) of the material optical properties, such as transient optics, detectivity, or single exciton property in such structures.
The present Special Issue of Nanomaterials aims to present the current state of the art in the use of structure regulation and physical property characteristics of these nano-optoelectronic materials for optoelectronic devices. In this issue, we invite contributions from leading groups in the field with the aim of giving a balanced view of the current 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 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.
