Special Issue Information

Dear Colleagues

The use of conventional semiconductors for heterojunction-based electronic devices is facing a bottleneck after the urgent requirement of the market to reduce the dimensions below the quantum limit. Since the first synthesis of graphene, research developed towards the possible use of new materials that are able to substitute Si in most devices as transistors, photodetectors, particle detectors, or solar cells, to mention but a few of the most popular option. At the same time, new phenomena, such as Majorana Fermions, superconductivity and low dimensional related effects, emerged at the interface between different materials opening new and exciting perspectives for fast electronics. Very recently, new materials have demonstrated their feasibility to substitute or integrate Si for heterojunction-based electronic devices. Their distinguished characteristics are a simple mechanism of growth down to few atomic layers, integration with traditional semiconductors (Si, Ge, GaAs, etc.), optical properties which overcome the limit of the Si absorption band, high carrier mobiltity at room temperature, easy doping, possibility to be deposited on different substrates, possible flexibility, etc. Topological insulators, transition metal dichancogenites and trichalcogenites, and black phosphorus are only some of the new materials where recent research has focused its attention. In addition, superconductor heterojunctions remain a valid alternative for their high efficiency and low electrical noise, at least for quantum computing and particle detection.

The aim of this Special Issue is to collect a number of papers dealing with the most innovative materials for heterojunction achievement with reliable properties for electronic, optical, and particle detection applications, as well as for emerging new interface effects. In addition to the interest in the specific materials, new fabrication methods, new applications, and possible interdisciplinarity are welcomed.

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 2000 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.
