Special Issue Information

Dear Colleagues,

Wide-bandgap materials (WBMs) featuring bandgap energies above 2 eV have attracted significant attention for their potential to drive a paradigm shift in high-speed power electronics and advancements in clean energy due to their excellent carrier mobility and remarkable stability in high-voltage, high-frequency, and harsh environmental conditions. Other prominent inherent material properties of WBMs, such as broadband optical transparency and high mechanical strengths, have recently been demonstrated as beneficial to optical/photonic and acoustic/phononic applications as well. For instance, gallium nitride (bandgap of ~3.4 eV), empowering energy-efficient and environmentally friendly blue-light-emitting diodes (LEDs), has reshaped the field of illumination technology. Hallmark WBMs, diamond (bandgap of ~5.5 eV), and silicon carbide (bandgap of 2.4–3.3 eV depending on the polytype) have emerged as the leading quantum photonic platforms hosting single-photon emissions and long-coherent spin states at room temperature. The combination of wide-bandgap and piezoelectric features endorses aluminum nitride (bandgap of ~6.4 eV) and lithium niobate (bandgap of ~3.8 eV) as promising structural materials for nano-/micro-electromechanical systems (N/MEMSs).

This Special Issue seeks to celebrate the advances in wide-bandgap materials, including, but not limited to, diamond, silicon carbide (SiC), gallium nitride (GaN), aluminum nitride (AlN), lithium niobate (LiNbO3), hexagonal boron nitride (h-BN), and gallium oxide (Ga2O3), as well as to showcase research papers, communications, and review articles related to their applications in photonics and phononics. Theoretical studies (such as first-principle prediction and device design) and experimental works (such as materials synthesis and characterization, device fabrication and measurements, system integration and packaging) are all considered to be within the scope of this Special Issue.

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.
