New electron interference effects in ballistic transport of semiconductor nanostructures have been theoretically studied. It is shown that for a number of 2D and 1D nanostructures in the form of joints of narrow and wide quantum wells (QWs) a transverse distribution of quantum‐mechanical current density is reproduced at a definite distance X 1 from the joint and splits into p identical profiles of p times lower intensity at the distance X 1 / p . This picture is reproduced periodically in cross‐sections X q = qX 1 ( p and q are integer). Various joints of rectangular and parabolic QWs have been studied. Possibilities for using and control of the effects are discussed.
