Ia. Dynnikov et Ay. Maltsev, TOPOLOGICAL CHARACTERISTICS OF ELECTRONIC-SPECTRA OF SINGLE-CRYSTALS, Journal of experimental and theoretical physics, 85(1), 1997, pp. 205-208
The paper considers the topological characteristics of dispersion func
tions epsilon(s)(p) in energy bands in single crystals related to clas
sical electron trajectories in uniform magnetic fields. Specifically,
the topological properties of open trajectories in p-space on various
energy levels within one energy band and related physical effects are
described. (C) 1997 American Institute of Physics.
