Before revision: Etched ion tracks in polyethylene terephthalate |Strain-fields (bright) around ion-track cores in FeCr2O4 Ion tracks are damage-trails created by swift heavy ions penetrating through solids, which may be sufficiently-contiguous for chemical etching in a variety of crystalline, glassy, and/or polymeric solids.
