Abstract
A method for manufacturing a gas sensor may be provided, the method comprising the steps of: preparing a porous base substrate; providing, on the porous base substarte, a source solution having graphene dispersed in a base solvent; manufacturing a graphene-impregnated base substrate by means of a driving process; and forming a first electrode and a second electrode on the graphene-impregnated base substrate.
Claims4
A gas sensor comprising:
- a porous base substrate comprising a porous structure;
- graphene disposed within the porous structure and also disposed on a surface of the porous base substrate;
- and
- first and second electrodes disposed on the porous base substrate,
- wherein the porous structure has a form of a hole extending from an upper surface toward a lower surface of the porous base substrate, and
- wherein a depletion layer and a hole accumulation layer are formed between the graphene and the porous base substrate in the hole of the porous structure.
