Special Issue Information
Dear Colleagues,
Wide-bandgap nitride semiconductors (such as gallium nitride, aluminum nitride, and boron nitride) are ideal materials for manufacturing high-performance optoelectronic and power devices due to their exceptional physical and chemical properties. However, the lack of high-quality homogeneous substrates, coupled with the limitations of low-quality homogeneous and heterogeneous substrates, results in poor regrown crystal quality and high dislocation densities, severely restricting device performance. To fundamentally address this bottleneck, this Special Issue focuses on the growth and precision processing technologies of nitride bulk single crystals. It highlights breakthroughs in advanced growth methods—such as hydride vapor phase epitaxy, the flux method, the high-pressure ammonothermal method, and physical vapor transport—in areas including crystal defect control, stress regulation, and large-scale preparation. Additionally, it provides an in-depth analysis of key processes in substrate processing, such as cutting, grinding, chemical mechanical polishing, and surface treatment, aiming to achieve the preparation of low-damage, atomically flat nitride single crystal substrates. This Special Issue aims to promote synergistic innovation in crystal growth and processing technologies, providing high-quality substrate materials for homoepitaxy and laying the foundation for the development of next-generation semiconductor technology.

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 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.
