Special Issue Information
Dear Colleagues,
In order to increase the radiation hardness of silicon radiation detectors, sensors with a three-dimensional array of electrodes that penetrate into the detector bulk were proposed by S. Parker et al. in 1999. The advantage of this geometry is to set the maximum drift and depletion distance by the electrode spacing rather than by the detector thickness as in the more conventional planar technology. The advantage of this structure includes short collection distances, fast collection times, and low depletion voltages, depending on the electrode diameter and pitch chosen.
The success of this geometry obtained combining VLSI and MEMS (Micro Electro Mechanical Systems) technologies was clear when they were selected for the innermost layer of the ATLAS IBL experiment. The detectors were produced matching the pixel readout electronic geometry and have been in use since 2014 at CERN experiments.
Different applications have benefited from advancements in 3D detector technologies. For instance, new micro-dosimeters that can measure the linear energy transfer (LET) of ionizing particles at cellular levels were developed recently at CNM-IMB. At the same time, highly efficient neutron detectors with trenches or 3D detectors made in diamond were also developed by several research groups around the world.

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.
