FAQ

Common questions about this product

Quick answers on material selection, customization, testing and ordering.

Yes. GaN templates are primarily designed as epi-ready platforms for subsequent GaN or related III-nitride epitaxy, helping simplify the growth process and provide a controlled crystalline surface.

Yes. In addition to GaN templates, PWG can provide AlGaN and InGaN templates for applications requiring bandgap engineering, particularly advanced UV, visible-light, and other optoelectronic devices.

A GaN template consists of a thin GaN epitaxial layer grown on a foreign substrate (e.g., sapphire or Si), offering a cost-effective platform for device regrowth. A freestanding GaN substrate is a bulk GaN wafer with the foreign substrate removed, providing the highest crystalline quality and thermal performance for high-end devices.

Yes. PWG is R&D friendly with flexible MOQ for prototyping. We support rapid customization of epi thickness, doping, and substrate types to match your device requirements.
