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

Submission

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. Papers will be published continuously (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as 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 refereed through a 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 quarterly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. For the first couple of issues the Article Processing Charge (APC) will be waived for well-prepared manuscripts. English correction and/or formatting fees of 250 CHF (Swiss Francs) will be charged in certain cases for those articles accepted for publication that require extensive additional formatting and/or English corrections.

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
