Special Issue Information
Dear Colleagues,
Microsystems technology continues to grow rapidly. Silicon is currently the dominant platform for Microsystems technology. The material possesses both favourable electrical and mechanical properties to create micro devices and systems. Silicon-based Microsystems leverage the batch fabrication paradigm and benefit from large body of knowledge around masking, deposition, growth, modification and structuring techniques.
But silicon does have some limitations. Silicon softens dramatically ad dopants diffuse at high temperature. Standard silicon based devices can no more be used at temperatures higher 150°C. In order to develop new generation of devices, which can survive and operate properly in such harsh environments well beyond regimes of silicon based devices, new materials and technologies are necessary.
Two-dimensional (2D) materials like graphene, transition_metal dichalcogenides (TMCs like MoS2 and WS2) …have drawn extensive attention since the discovery of graphene through the method of mechanical exfoliation by Geim’s group in 2004. 2D materials show outstanding and fascinating mechanical, electronic, thermal and optical properties. Graphene has an ultra-high intrinsic mobility (200000 cm2V-1s-1 compared to silicon’s) and conductivity (~500 W-1K-1 compared to silicon’s), excellent thermal conductivity, and very high Young’s modulus (~ 1 TPa compared to silicon’s Young’s modulus of 160MPa).
The TMDCs materials exhibit exotic properties, for example a tunable band gap, which is absent in graphene. TMCs are emerging materials that hold great promise for their use in a wide range of applications, from batteries and flexible electronics to biosensors and water-purification systems.
The new 2D materials have been explored in a wide range of applications such as sensors, nano electronics, optoelectronics, spintronics, supercapacitors, solar cells and purification systems.
The purpose of this Sensor Special Issue on 2D MATERIAL-BASED SENSING DEVICES is to get an overview of activities on developments of new deposition and growth methods of such 2D materials, fabrication technologies, new devices and systems such as sensing elements, electronic circuits, solar cell, purification components and also testing and characterization of such systems.

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. Micromachines is an international peer-reviewed open access monthly 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.
