    "abstract": "We present an electron interferometer based on near-field diffraction from\ntwo nanostructure gratings. Lau fringes are observed with an imaging detector,\nand revivals in the fringe visibility occur as the separation between gratings\nis increased from 0 to 3 mm. This verifies that electron beams diffracted by\nnanostructures remain coherent after propagating farther than the Talbot length\n$z_T = 2d^2/\\lambda$ = 1.2 mm, and hence is a proof of principle for the\nfunction of a Talbot-Lau interferometer for electrons. Distorted fringes due to\na phase object demonstrates an application for this new type of electron\ninterferometer.",
