Special Issue Information

Dear Colleagues,

It is known that, since tens years ago, semiconductor nanomaterials belonging to the commonly-known low-dimensional (LD) systems, are the subject of high scientific interest, both from the point of view of fundamental science, as well as for their technological applications. This is related to fact that LD semiconductor nanomaterials being smaller than 100 nm in one dimension exhibit specific and fascinating properties for which their surfaces begin playing a crucial role and causing the novel and potentially exceptional characteristics that are completely different with respect to their bulk. These characteristics determine the most potential semiconductor nanomaterials applications.

This Special Issue will be dedicated to a comprehensive overview of current knowledge related to the surface of low-dimensional semiconductor nanomaterials, on aspects of their potential applications.

Contributions are invited on a wide range of topics in this general research area, including both reviews and research articles, with a special emphasis on (but not limited to):

  • Controlled synthesis of high-quality semiconductor nanomaterials of well controlled surfaces,
  • Advanced characterization, including modelling of the surface of semiconductor nanomaterials over different length scales, including their chemical, electronic, morphological and optical properties, with respect to their application,    
  • Applications of semiconductor functional nanomaterials of well-controlled surfaces in the development of specific semiconductor nanodevices for, among others, nanoelectronics, optoelectronics, and spintronics.

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. Crystals 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.

Keywords

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.

A relatively new approach to the design of photocatalytic and gas sensing materials is to use the shape-controlled nanocrystals with well-defined facets exposed to light or gas molecules. An abrupt increase in a number of papers on the synthesis and characterization of metal oxide semiconductors such as a TiO2, α-Fe2O3, Cu2O of low-dimensionality, applied to surface-controlled photocatalysis and gas sensing, has been recently observed. The aim of this paper is to review the work performed in this field of research. Here, the focus is on the mechanism and processes that affect the growth of nanocrystals, their morphological, electrical, and optical properties and finally their photocatalytic as well as gas sensing performance.

In this paper, the thermoelectric properties of In2O3-based materials in comparison with other thermoelectric materials are considered. It is shown that nanostructured In2O3 Sn-based oxides are promising for thermoelectric applications at moderate temperatures. Due to the nanostructure, specific surface properties of In2O3 and filtering effects, it is possible to significantly reduce the thermal conductivity and achieve an efficiency of thermoelectric conversion inaccessible to bulk materials. It is also shown that a specific surface state at the intergrain boundary, optimal for maximizing the filtering effect, can be achieved through (1) the engineering of grain boundary parameters, (2) controlling the composition of the surrounding atmosphere, and (3) selecting the appropriate operating temperature.
