Special Issue Information

Dear Colleagues,

This Special Issue of Photonics focuses on new research results and practical solutions in the fields of two-dimensional (2D) crystal photonics, optoelectronics, and electronics. 2D crystals have received much attention in recent years, because of their unusual properties (which are associated with their ultra-thin thickness and 2D morphology). The discovery of graphene, i.e., a single atomic layer of carbon, can be considered a defining point in the research and development of stable, truly 2D material systems. Besides graphene, other types of 2D nanomaterials, such as transition metal dichalcogenides, have also been studied and applied in various applications, including in electronics, optoelectronics, and energy storage devices.

This Special Issue covers a large scope of research in 2D crystal photonics, optoelectronics, and electronics, and solicits contributions in, but not limited to:

Electronic band structure and current transport of 2D crystals
Light-matter interaction in 2D crystals
Interactions of 2D crystals with their substrates and environment
Photonic and optoelectronic devices based on 2D crystals, including photo-detectors, light emitting diodes, optical modulators, lasers, optical frequency converters, polarizers, terahertz devices, waveguides, etc.
Electronic devices based on 2D crystals for logic, analog, and power applications
Plasmonic devices and metamaterials based on 2D crystals
Heterostructures of 2D crystals
Batteries, fuel cells, photovoltaic cells, and super-capacitors based on 2D crystals for energy storage
Flexible photonic and electronic devices based on 2D crystals
Sensors based on 2D crystals for medical and biological applications

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. Photonics 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 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.

Abstract

Few-layer graphene films were synthesized through chemical vapor deposition technique using coal char as solid carbon source. Raman spectroscopy, X-ray diffraction, transmission electron microscopy, and selected area electron diffraction were used to characterize the graphene films. The electrochemical performance of the coal char derived few layer graphene anodes for lithium ion batteries was investigated by charge/discharge curves and discharge capacity at different current densities. The graphene anode maintained the reversible capacity at ~0.025, 0.013, and 0.007 mAh/cm2 at a current density of 10, 30, and 50 µA/cm2, respectively. The coal char derived graphene anodes show potential applications in thin film batteries for nanoelectronics. Full article
