Highly sensitive NO2 gas sensors based on heterostructured p-rGO/n-Ga2O3 nanorods

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 b...
