Special Issue Information

Dear Colleagues,

We would like to invite you to contribute your work to the Special Issue of Materials titled “Functional Surface Structures and Thin Solid Films”.

Nanostructures at surfaces, such as supported nanoparticles, nanowires, molecular arrays, 2D materials, and thin solid films, exhibit unique physico-chemical properties, originating both from their low-dimensionality and the interaction with the substrate on which they grow. Recent advances in nanostructure fabrication, experimental atomic-scale characterization, and theoretical modeling, allow the determination of the structure–properties relationships in such systems and the studies of the underlying physical and chemical mechanisms. Hybrid nanostructures, such as nanoparticles supported on thin solid films or intercalated epitaxial graphene, allow us to combine the properties of different materials and fine-tune the mutual interactions through the well-defined interfaces formation. This results in a wide range of potential applications of supported nanostructures in various industrial fields, such as nanoelectronics/spintronics, data storage, heterogeneous catalysis, or gas/bio- sensing.

This Special Issue will feature articles devoted to the preparation and physico-chemical characterization of surface nanostructures, focusing on the determination of structure–properties relationships. The submission of both experimental and theoretical reports is cordially invited. We believe that “Functional Surface Structures and Thin Solid Films” will become a valuable bibliographic resource for scientists working on experimental and theoretical aspects of nanostructures at surfaces.

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 papers will be 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. Materials 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 1800 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.

In the present investigation, a nitrogen-doped multilayer homoepitaxial single crystal diamond is synthesized on a high-pressure high temperature (HPHT) Ib-type diamond substrate using the microwave plasma chemical vapor deposition (MPCVD) method. When 0.15 sccm of nitrogen was added in the gas phase, the growth rate of the doped layer was about 1.7 times that of the buffer layer, and large conical and pyramidal features are formed on the surface of the sample. Raman mapping and photoluminescence imaging of the polished cross sectional slice shows a broadband emission, with a characteristic zero phonon line (ZPL) at 575 nm in the doped layers, and large compressive stress was formed in the nitrogen-doped layers. X-ray topography shows that the defects at the interface can induce dislocation. The pyramid feature is formed at the defect, and more nitrogen-related defects are formed in the pyramid region. Thin nitrogen-doped multilayers were successfully prepared, and the thickness of the nitrogen-doped and buffer layers was about 650 nm each. The indentation measurements reveal that the thin nitrogen-doped multilayers are ultra-tough (at least ~22 MPa m1/2), compared to the Ib-type HPHT seed substrate (~8 MPa m1/2) and the unintentionally doped chemical vapor deposition (CVD) single crystal diamond (~14 MPa m1/2).
