Vi. Ilin et al., QUANTUM-SIZE LAYERED PBS C STRUCTURES DEPOSITED BY PULSED-LASER EVAPORATION IN VACUUM/, Materials science & engineering. B, Solid-state materials for advanced technology, 35(1-3), 1995, pp. 120-124
Layer quasiperiodical structures (Fibonacci superlattices) were grown
by pulse laser deposition on thin glass and BaF2 substrates. The optic
al spectrum in the IR region shows peculiarities connected with the se
misimilarity of the energy spectrum of the density of states. The loca
lization of carriers in the quasiperiodical superlattice, which increa
ses in an electric field and on cooling, causes a decrease in optical
transparency of the superlattice.
