Special Issue Information

Dear Colleagues,

In 2004, A. Geim and K. Novoselov, from the University of Manchester, opened a new path in physics and electronic applications when they discovered an easy way to produce graphene, a two-dimensional (2D) allotrope of carbon. Since then, the interest in graphene and, more recently, other two-dimensional materials (such as MoS2, silicene, hexagonal boron nitride, and black phosphorous) has risen exponentially. While graphene shows excellent monopolar carrier transport properties, alternative 2D materials have the potential to provide digital applications with ultra-scaled devices featuring nanometer gate lengths. In general, the atomic-scale thickness of these materials, their large surface-to-volume ratio, and their excellent electronic and mechanical properties make them interesting candidates for future electronic devices capable of offering exciting new applications in, among other things, flexible electronics, high-frequency applications, optoelectronics, and sensors. However, such promising applications will only be possible with much research effort at all levels. Techniques for producing such 2D materials in a viable way for industrial manufacturing, material and device modeling, characterization, and prototype development are all necessary to make 2D materials viable in the future.

For this Special Issue, we welcome the submission of original research articles, communications, and reviews on recent advances in graphene and/or novel 2D materials and the electronic devices, sensors, and applications that use them.

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.

Unidimensional photonic crystal-based biosensors have gained much attention in the area of blood glucose measurement. In this paper, we propose two novel designs based on two-dimensional (2D) Van der Waals materials. The first 1D photonic crystal design consists of multilayers of 2D gallium sulfide and 2D muscovite mica [GaS/Mica]ND[GaS/Mica]N, and the second design consists of multilayers of 2D gallium sulfide [GaS/G]ND[GaS/G]N. We conducted a numerical analysis using the transfer matrix method to investigate the properties of photonic crystals, both with and without defect layers, in order to assess their suitability for biosensing applications. The biosensors’ performances were investigated as a function of glucose concentration, revealing a high sensitivity of 832 nm/RIU, a notable figure-of-merit of 1.46 × 105 RIU−1, a Q-factor exceeding 105, and a minimum limit of detection of 3.4 × 10−7 RIU. Finally, we modified the [GaS/G]ND[GaS/G]Nstructure in order to enhance the sensitivity nearly 5-fold. The proposed biosensors offer the advantage of being label-free, making them promising platforms for the sensitive and reliable detection of blood glucose levels. Full article
