Poštovani,
Podsjećamo Vas na današnji seminar na Institutu za fiziku
u 15 sati (u zgradi Mladen Paić), koji će održati Venera Nasretdinova,
"Institute of Radioengineering and Electronics of the Russian Academy
of Science" u Moskvi.
Venera Nesretdinova je gošća na Institutu za fiziku u sklopu
zajedničke suradnje s Damirom Starešinićem.
Sažetak predavanja je u nastavku poruke
PHOTOCONDUCTION STUDY OF ENERGY STRUCTURE OF TAS3 AND SOME
OTHER QUASI-ONE-DIMENSIONAL CONDUCTORS

Energy structure of the Peierls gap in charge density wave systems
orthorhombic TaS3, NbS3 and blue bronze K0.3MoO3 was examined by
spectral study of photoconduction. In o-TaS3 the gap edge and energy
levels inside the Peierls gap are observed. The amplitude of those
energy levels is found to depend on both the temperature and the
electric field of the order of 10 V/cm. The small value of the
electric field indicates participation of the collective state in
formation of the energy levels inside the Peierls gap. In NbS3 and
K0.3MoO3 only the edges of the Peierls gap are observed. In contrast
with o-TaS3 no energy levels are observed inside the Peierls gap for
both of these compounds.
