Energy dispersion curve

There has been one lattice dynamics study of leucite by inelastic neutron scattering (Boysen 1990). The low-energy dispersion curves were measured for the high-temperature cubic phase along a few symmetry directions in reciprocal space. The results... 

Fig.5.2-2tr Energy dispersion curves E k ) around X of the SBZ for Ag(lOO). Projected bands and surface state features A and B are the same as in Pig. 5.2-8a. Experimental points are obtained by electroreflectance (1) and KRIPES (2 and 3). Curve (3) represents image states [2.34,35]...

Fig. 5.2-25 Energy dispersion curves E k ) around E point of the SBZ for Ag(lll). Experimental data from ARUPS are fitted with a parabolic band with ra /rao = 0.53 [2.36]...

Fig. 19. Calculated electron energy dispersion curve for Si(lll) in the energy optimized TT-bonded chain structure. The experimental points have been shifted upwards by 0.3 eV so that the theory and experiment are aligned at the J point. (after Ref. 59)... 

Energy dispersion curves as a function of the helical angle in the case of (a) a single degenerate transition (b) a doubly degenerate transition - l/d=2. 

In practice, as the energy dispersion curves depend on the crystal direction, m is tensorial.)... 

If one considers a one-dimensional (1-D) line of atoms in the limit of no electron interaction (free electron approximation), the energy dispersion curve (E vs. fc) is parabolic since E I as shown in Figure 19.1. Actually, the curve is not continuous, but a locus of...
