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.
