Highly sensitive NO2 gas sensors based on heterostructured p-rGO/n-Ga2O3 nanorods
In this study, using a sensing membrane composed of p-type reduced graphene oxide (rGO)-decorated hydrothermally synthesized n-type gallium oxide (Ga2O3) nanorods, nitrogen dioxide (NO2) gas sensors were successfully fabricated.The characteristics of the rGO-decorated Ga2O3 nanorods were analyzed by X-ray photoelectron spectroscopy (XPS).The experi
