Claim:
1. A method for forming a laser-patterned two-dimensional material, comprising: focusing a pulsed laser beam on a two-dimensional material along a desired path; wherein at least one of a wavelength, a beam shape, an optical fluence, a pulse width, and a pulse repetition rate of the pulsed laser beam is configured to cause the pulsed laser beam to ablate atoms from the two-dimensional material to form a channel in the two-dimensional material along the desired path without damaging the remainder of the two-dimensional material not illuminated by the pulsed laser beam; and wherein the two-dimensional material is grown by chemical vapor deposition (CVD), a first layer of the two-dimensional material being patterned on a bottom surface thereof before the growth of a second layer of the two-dimensional material on a top surface of the first layer.
