Abstract

Scanning tunneling microscopy (STM) rind noncontact atomic-force microscopy (AFM) have been used to investigate the 4 x 1 and 1 x 2 reconstructions of SnO2(110). These terminations were prepared by sequential annealing in UHV at temperatures of 900 and 1075 K, respectively. Two coexisting 4 x 1 structures are observed with STM, one of which is consistent with previously reported STM images, the other appearing to arise from a SnO(101) overlayer. For the 1 x 2 ph:ase, a combination of STM and noncontact AFM images point to an added-row morphology.
