Abstract
This disclosure provides systems, methods, and apparatus related to few-layer and monolayer hexagonal boron nitride having a pore therein. In one aspect, a method comprises providing a sheet of hexagonal boron nitride (h-BN). A defect is created in the sheet of h-BN. The sheet of h-BN is heated to a temperature above about 500° C. The defect in the sheet of h-BN is irradiated with charged particles to enlarge the defect to a hexagonal-shaped pore or a parallelogram-shaped pore in the sheet of h-BN.
Claims20
A method comprising:
- (a) providing a sheet of hexagonal boron nitride (h-BN);
- (b) creating a defect in the sheet of h-BN by depositing a catalyst on the sheet of h-BN and heating the catalyst;
- (c) heating the sheet of h-BN to a temperature above about 500° C.;
- and
- (d) irradiating the defect in the sheet of h-BN with charged particles to enlarge the defect to a hexagonal-shaped pore or a parallelogram-shaped pore in the sheet of h-BN.
