Special Issue Information

Dear Colleagues,

The inventions of scanning tunneling microscopy (STM) in 1980 and atomic force microscopy (AFM) in 1985 revolutionized the nano-scale characterization of materials surfaces. While the application of STM is limited to conductive materials, AFM can be applied on virtually any materials, from soft (living cells, tissues, gels, and polymers) to hard (metals, ceramics, and glasses).

In scanning probe microscopy (SPM), a micro-manufactured cantilever with a nano-sized tip at its end is used to probe interactions with a sample surface. Meanwhile, cantilevers with various stiffness and tips with different sizes and of different chemistries are available. Once used to image the surface morphology of samples, SPM has become a versatile method to probe various interactions between a tip and a sample surface, such as mechanical, thermal, electrical, and magnetic. Furthermore, AFM can be used in different environmental conditions from ultrahigh vacuum to chemically aggressive. With these developments, SPM is now an unavoidable tool to characterize the response of materials and devices to various solicitations with nanometer resolution and beyond.

We invite researchers to contribute to the Special Issue on “Applications of Scanning Probe Microscopy (SPM)—Methods in Materials Science”. This Special Issue is intended to serve as a forum covering recent developments and applications of SPM in the field of materials science. Potential topics include but are not limited to:

  • Nano-mechanics of materials and devices;
  • Micro- and meso-structural characterization of materials;
  • Characterization of surface and buried defects;
  • Characterization of electronic materials and their devices;
  • Corrosion and surface chemistry of materials.

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. 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 2600 CHF (Swiss Francs).

The ferroelectric domain surface charge dynamics after a cubic-to-tetragonal phase transition on the BaTiO3 single crystal (001) surface was directly measured through scanning probe microscopy. The captured surface potential distribution shows significant changes: the domain structures formed rapidly, but the surface potential on polarized c domain was unstable and reversed its sign after lengthy lapse; the high broad potential barrier burst at the corrugated a-c domain wall and continued to dissipate thereafter. The generation of polarization charges and the migration of surface screening charges in the surrounding environment take the main responsibility in the experiment. Furthermore, the a-c domain wall suffers large topological defects and polarity variation, resulting in domain wall broadening and stress changes. Thus, the a-c domain wall has excess energy and polarization change is inclined to assemble on it. The potential barrier decay with time after exposing to the surrounding environment also gave proof of the surface screening charge migration at surface. Thus, both domain and domain wall characteristics should be taken into account in ferroelectric application. Full article
