Special Issue Information

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 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. 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 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.

A high-performance temperature sensor based on a p-GaN/AlGaN/GaN hybrid anode diode (HPT-HAD) fabricated by hydrogen plasma treatment is demonstrated. The sensor exhibits accurate and stable temperature responses from 73 to 573 K. The forward anode voltage is linearly proportional to the temperature over the measured temperature range at a fixed current. At a forward current density of 10−7 mA/mm, the device achieves a maximum sensitivity of 1.93 mV/K. The long-time anode current stress measurement reveals that the HPT-HAD shows almost no degradation even at 573 K for 1 h at a current of 100 μA, and the anode voltage shifts only 120 mV at 573 K for 1000 s at 1 nA. This work shows that the HPT-HAD temperature sensor can be reliably operated over a wide temperature range from cryogenic to high temperatures, so can be used in a variety of extreme environments.
