Nearly nondiffracting electron lattice beams generated by polygonal slits

A method for generating electron lattice beams carrying vortices using nanofabricated polygonal slits in a transmission electron microscope is proposed. Experimental and simulation study of the intensity of the beams verified their Bessel beam-like nearly nondiffracting behavior. Phase analysis usin...
