After receipt of his doctorate, Brillouin became the scientific secretary of the reorganized Journal de Physique et le Radium. In 1932, he became associate director of the physics laboratories at the Collège de France. In 1926, Gregor Wentzel, Hendrik Kramers, and Brillouin independently developed what is known as the Wentzel–Kramers–Brillouin approximation, also known as the WKB method, classical approach, and phase integral method. In 1928, after the Institut Henri Po…
The first Brillouin zone is the locus of points in reciprocal space that are closer to the origin of the reciprocal lattice than they are to any other reciprocal lattice points (see the derivation of the Wigner–Seitz cell). Another definition is as the set of points in k -space that can be reached from the origin without … See more In mathematics and solid state physics, the first Brillouin zone is a uniquely defined primitive cell in reciprocal space.
