摘要：

Structures of two kinds of wide strands with different height formed on nonstoichiometric TiO2-x(1 1 0) surfaces are discussed based on atom-resolved STM images. Bright strands, which form linked (1 x 2) structure with single links and cross-links, consist of double strands of Ti2O3 added rows. A structural model of the linked (1 x 2) structure as well as its formation mechanism are discussed. Dark strands (DS) consist of triple strands, whose center row shows unique bias dependency on STM images. A structural model is proposed for the DS. (C) 2002 Elsevier Science B.V.
