Special Issue Information

Dear colleagues,

As far as we know, the applications of nanomaterials are limitless and offer the possibility to generate significant advances in fields such as computing, electronics, food, medicine, etc. The variety of nanomaterials is huge, and their combination allows to tailor the properties of functional materials to develop novel devices and applications.

In particular, electronics in nanomaterials is one of the scientific disciplines at the forefront of the fast-emerging fields of nanoscience and nanotechnology. Nanoelectronics holds answers for how the capabilities of electronic devices can be increased while reducing their weight and consumption. Additionally, the possibility of eternally shrinking integrated circuits, wearing flexible gadgets, spreading internet-of-things everywhere, etc. is becoming a reality thanks to nanotechnology.

Similarly, very interesting magnetic behaviors can be produced in materials thanks to the nanometric dimensions of the systems or of the crystallites forming them. Potential applications in nonreciprocal systems, magnetic recording, high-performance soft materials and magnets, microsensors and microactuators, functionalized magnetic particles, etc. are being revolutionized by developoments in nanomagnetism.

This Special Issue of Nanomaterials aims to explore the applications of nanomaterials, including the fields of electronics, magnetism, spintronics, etc.

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 papers will be 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. Nanomaterials 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 2000 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.

Carbon nanotube (CNT) cold cathodes are proving to be compelling candidates for miniaturized terahertz (THz) vacuum electronic devices (VEDs) owning to their superior field-emission (FE) characteristics. Here, we report on the development of a multi-sheet beam CNT cold cathode electron optical system with concurrently high beam current and high current density. The microscopic FE characteristics of the CNT film emitter is captured through the development of an empirically derived macroscopic simulation model which is used to provide representative emission performance. Through parametrically optimized macroscale simulations, a five-sheet-beam triode electron gun has been designed, and has been shown to emit up to 95 mA at 3.2 kV. Through careful engineering of the electron gun geometric parameters, a low-voltage compact THz radiation source operating in high-order TM 5 , 1 mode is investigated to improve output power and suppress mode competition. Particle in cell (PIC) simulations show the average output power is 33 W at 0.1 THz, and the beam–wave interaction efficiency is approximately 10%. Full article
