Abstract:

The surface of a fresh cleavage of TiS2, TiSe2, and TiTe2 crystals has been investigated using scanning tunneling microscopy with atomic resolution. All materials are characterized by triangular defects coinciding in shape with those supposedly formed as a result of the local change in the titanium atom coordination from octahedral to trigonal-prismatic by the chalcogen due to the Jahn-Teller effect. The conclusion has been drawn that the Jahn-Teller effect exists in these materials, but it is responsible for the formation of nanodefects rather than for the transition to a charge-density wave state. It has been shown that this interpretation of defects allows one to understand the evolution of the stability boundary of a charge-density wave upon donor and acceptor doping.
