Low-temperature reconstruction pathway to the Si(111)({radical}3{times}{radical}3){ital R}30{degree}-Ag interface
- Department of Physics and Astronomy, The University of Tennessee, Knoxville, Tennessee 37996 (United States)
Using the spectroscopic capabilities of a scanning tunneling microscope, we identified and investigated a low-temperature {ital reconstruction} {ital pathway} for forming Si(111)({radical}3{times}{radical}3){ital R}30{degree}-Ag from the Si(111)3{times}1-Ag interface. A metastable intermediate phase consisting of one-dimensional atom chains atop the Si(111)3{times}1-Ag reconstruction stabilizes {ital locally}. The density of states at the chains indicates a Ag-Si bonding configuration similar to that of the ({radical}3{times}{radical}3){ital R}30{degree} reconstruction. We propose a mechanism for the (3{times}1) to ({radical}3{times}{radical}3){ital R}30{degree} phase transformation at low temperature. {copyright} {ital 1996 The American Physical Society.}
