Abstract
Official abstract text for this publication.
Provided are a method of detecting a grain boundary of graphene and a device using the same.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of detecting a grain boundary of graphene, the method comprising oxidizing a catalytic metal by reacting a stack of the catalytic metal and graphene with 30 to 40 wt % of an aqueous hydrogen peroxide solution, wherein an amount of the aqueous hydrogen peroxide solution is in a range of 0.001 to 1 L based on 1 m 2 of a unit area of the stack of the catalytic metal and graphene, and wherein the aqueous hydrogen peroxide solution further comprises a dispersant, a stabilizer or a combination thereof in an amount of 1 to 15 wt % based on a total weight of the aqueous hydrogen peroxide solution. 2. The method of claim 1 , wherein the catalytic metal comprises at least one selected from cobalt (Co), gold (Au), silver (Ag), aluminum (Al), chromium (Cr), magnesium (Mg), manganese (Mn), molybdenum (Mo), rhodium (Rh), silicon (Si), titanium (Ti), tungsten (W), uranium (U), vanadium (V), palladium (Pd), yttrium (Y), zirconium (Zr), germanium (Ge), and an alloy thereof. 3. The method of claim 1 , wherein the catalytic metal is oxidized for 1 sec to 10 min.
