# gst: to create standing waves induced by mismatches

<< In work recently published (..), the mismatch of electronic momentum across domain walls (i.e., regions with a different orientation of the intrinsic electric dipole) is shown to create standing waves, even though there is no potential buildup across the domain wall. >>
