... We consider in Fig. 5 the analysis for a square lattice. The equation of the zone boundaries is 2kG G2 0 and is satisfied if k terminates on the plane normal to G at the midpoint of G. The first Brillouin zone of the square lattice is the area enclosed by the perpendicular bisectors of G1 and o ...

If the a0 is much higher than this, then electron cavitation [16] can compete with plasma wave generation and produce an ion column, which is a region devoid of plasma electrons. S ...
