Claim:
1. A method of forming a nanopore in a nanometric material, the method comprising: forming a nanopore nucleation site in a nanometric material, the nanometric material having a thickness that is less than about 5 nanometers, the nanopore nucleation site being formed at a location of the nanometric material that is interior to lateral edges of the nanometric material by directing a first energetic beam, selected from the group consisting of ion beam and neutral atom beam, at the interior location with a beam energy that is at least that beam energy which provides at the nanometric material a bulk atom displacement energy of E forming a nanopore at the nanopore nucleation site by directing a second energetic beam, selected from the group consisting of electron beam, ion beam, and neutral atom beam, at the nanopore nucleation site with a beam energy that is less than that beam energy which provides at: the nanometric material a bulk atom displacement energy of E
