Photoacoustic Detection of H<sub>2</sub> and NH<sub>3</sub> Using Plasmonic Signal Enhancement in GaN Microcantilevers

Photoacoustic Detection of H<sub>2</sub> and NH<sub>3</sub> Using Plasmonic Signal Enhancement in GaN Microcantilevers

Photoacoustic (PA) detection of H<sub>2</sub> and NH<sub>3</sub> using plasmonic excitation in Pt- and Pd-decorated GaN piezotransistive microcantilevers were investigated using pulsed 520-nm laser illumination. The sensing performances of 1-nm Pt and Pd nanoparticle (NP) dep...
