An STM study of desorption-induced thallium structures on the Si(111) surface
Original language description
The scanning tunneling microscopy is used to study morphology of a Tl adlayer in various stages of Tl desorption from the Si(111) surface. Transition from the Si(111)/(1 x 1)-Tl structure through the (root 3 x root 3)R30 degrees mosaic phase to domains of metastable Si reconstructions is observed. Silicon substitutional atoms are found to be intrinsic to the (root 3 x root 3)R30 degrees structure. The temperature dependence of the amount of residual TI atoms on the surface is successfully fitted by a model using the first order desorption. The same desorption energy of (2.1 +/- 0.3) eV and frequency prefactor 5 x 10(14 +/- 2) s(-1) during all stages of the desorption are sufficient for the fitting. It is concluded that bonding of Tl in both (1 x 1) and(root 3 x root 3) configurations is of the same nature.
