Electrochemical Spectroscopies in Organic Electronics: Theory, Methods, Applications

Dear Colleagues,

Organic electronics applications are envisioned to address a broad market, which includes flexible displays, electronic papers, sensors, disposable and wearable electronics, and medical and biophysical applications, leading to a tremendous amount of interest from both academia and industry in the study of devices. These fields of science and technology constitute interdisciplinary fields that cover physics, chemistry, biology, and materials science, using new synthesized organic materials – organic semiconductors. On the other hand, we face the situation when the available organic electronics applications lack sometimes the theoretical background. The cause may be the complicated properties of disordered, weakly bonded molecular materials with properties different from their inorganic counterparts. One of the basic information-rich resources is the electronic structure of organic semiconductors, with both native and defect states, as well as excited states elucidated by the methods, hardly possible to be transferred from the branch of inorganic semiconductors, enabling the introduction of principles of gap engineering [2] to the branch of organic electronics [3].

The electrochemical spectroscopic methods fill with the advantage of this gap for studies of morphological, transport, and recombination properties of organic semiconductors and biophysical materials as will be shown in the prepared and compiled Special Issue “Electrochemical Spectroscopies in Organic Electronics”  on the topic.

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. Applied Sciences 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 2400 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.
