Structural, Electrical and Optical Properties of Semiconductor Alloys and Their Heterostructures

Dear Colleagues,

It is our dream to inaugurate new materials platforms to carry out the “on demand” functions that accomplish the novel technological possibilities in the 21st century, such as future computers that can achieve quantum supremacy, ultrasensitive sensors that immediately notify us of tiny environmental changes, supersmart personal wearable electronics, the ultrahigh-speed network that provides an unprecedented enrichment of our lives, and many other items. One of the keys to attaining these technological miracles is a class of semiconductor alloys and their heterostructures beyond silicon, in which the extraordinary effects of quantum mechanics give rise to exotic and often incredible properties. Although the discovery of semiconductors revolutionized computation and information storage and piloted in today’s hundred-billion-dollar electronics industry, research on traditional semiconductor alloys and their heterostructures still has great potential to renovate energy and energy-related technologies, to generate, store, and process qubits, to offer extraordinary advantages for high-speed, low-power electronics, and so on. Furthermore, it would be important to investigate a new frontier in the varieties of semiconductor systems, such as two-dimensional transition metal dichalcogenides and topological insulators that feature unprecedented capabilities, to dramatically improve our ability to synthesize, characterize, and control these materials. This Special Issue focuses on the mixture of prospective applications and open fundamental problems that aim to clarify new trends in the state of the art, to provide better understanding, and to breed exciting science and technology for many years to come.

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). 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.
