Nature Sub Series: Ultimate photothermal effect graphene airgel
Nature Sub Series:ultimate photothermal effect, the final proof of the graphene airgel light thermoacoustic (PTA) efficiency, depending on their particular thermal and optical properties, can be experimentally by reducing its mass density achieve.
is generated, amplified sound in a passive optical device, modulated sound mixing and harmonic distortion without the ability to completely change the acoustic field. Like the conventional speaker, light thermoacoustic (PTA) allow the conversion of light to effect sound, without any moving parts and a large amount of organic electrically connected. Also, PTA complementary metal oxide semiconductor device may be a standard silicon (CMOS) manufacturing technology integration. Here, we demonstrate the efficiency of the final PTA graphene airgel, depending on their particular thermal, and optical properties can be achieved experimentally by lowering its mass density. In addition, we show the performance of aerogels over the entire audible range omnidirectional source, no harmonic distortion.
