The Study of Radiation Effects in Emerging Nanoelectro Systems

Dear Colleagues,

Our future will take us into space, and we must safely navigate various radiation environments. Radiation can ionize and displace atoms. The effects of space radiation result in an increased ionizing dose, displacement damage, and single-event effects for electronics. A total ionizing dose is of concern due to the secondary radiation of energetic particles that are created when the energetic particles are slowed down through the intervening materials of the spacecraft. The interactions of galactic cosmic rays with atoms of various materials aboard spacecraft result in secondary neutrons that cause displacement damage. Single-event effects occur as galactic cosmic rays, particles from solar events, trapped protons, and secondary neutrons disrupt electronics, leading to equipment damage or failure. Now, the challenge is creating lightweight sensors for various radiation environments.

To meet these challenges, we need cutting edge research focused on radiation effects on materials system to explore their sensitivity to the broad radiation environment for safe space travel. The focus of this special edition is on radiation research with nanomaterials and perovskites and various materials systems for sensors in space. We invite you to submit your research work related to sensors for radiation and aerospace applications. This special edition will serve to help those interested in the sensor development in the space industry become familiar with the current state of the art of creating sensors and their potential for space applications. Potential topics include, but are not limited to, the following:

• Radiation effects on nanomaterials;
• Sensors made with perovskites;
• Radiation on International Space Station;
• Radiation effects on sensors for lunar applications;
• Radiation effects on sensors for Mars applications;
• Modelling of radiation effects on sensors and material 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 250 words) can be sent to the Editorial Office for assessment.

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. Nanomaterials 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.
