Abstract

PDA(Polydiacetylene)-supramolecules were successfully immobilized on the surface of Sc ₂O ₃/GaN/Sap-phire structures for use as selective NH ₃ gas sensors. The Sc ₂O ₃ was epitaxially grown on GaN/Sapphire templates by molecular beam epitaxy (MBE) to replace the non-uniform native Ga ₂O ₃. The GaN-based PDA gas sensors showed excellent selectivity for ammonia detection after the end-functional group was modified to respond to this specific gas species.
