High Electron Mobility Transistor (HEMT) Devices and Applications

Dear Colleagues,

Ever since the demonstration of the first high-electron mobility transistors (HEMTs) by Dr. Mimura in 1981, HEMTs have been developed rapidly and commercialized in different material systems for a myriad of applications. At the early development stage, AlGaAs/GaAs, GaAs/InGaAs, and InP-based HEMTs were widely implemented into high-speed electronics communication applications with excellent noise and power performance. The development of GaN HEMTs has opened the gate to more applications, such as power electronics, mm-wave frequency systems, biosensing, and radiation-hardened electronics. Recently, ultrawide bandgap materials such as AlGaN- and Ga2O3-based HEMTs have been introduced and demonstrated encouraging results. This Special Issue will cover innovative HEMT devices, applications based on HEMT technology, HEMT-related material research, including epitaxy growth, material characterization, and fabrication techniques, and HEMT simulation.

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. Crystals 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 2100 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.
