Dear Colleagues,                

Modern fabrication techniques allow the manipulation of matter at the nanoscale; thus, nanostructures presenting heterogeneous electronic properties can be obtained. These nanoarchitectures are the natural playground to study quantum matter, the latter being realized when the quantum behavior of the constituents significantly affects the system properties. Quantum matter presents sometimes emergent properties, of which superconductivity is a paradigmatic example. Emergent properties in quantum matter systems may require the notion of topological order, which is a relevant concept in topological insulators and topological superconductors.

The purpose of the Special Issue is to collect state-of-the-art contributions dealing with the characterization and modelling of low-dimensional heterostructures involving topological insulators, mesoscopic superconductors, graphene and other two-dimensional materials or thin films, and quantum dots with strong electronic correlations.

Contributions have to describe, among other potential topics, emergent quantum behaviors in low-dimensional heterostructures, such as topological phase transitions, surface or edge quantum states, proximity effects, anomalous scattering mechanisms (e.g., the Andreev reflection mechanism), etc.

Although both purely theoretical or experimental works (in the form of research papers or review articles) are welcomed, contributions in which the theoretical formulation is able to explain or provide insight into a real device response are preferred and solicited.

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. Nanomaterials 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 2900 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.
