- Abstract
- The adsorption of zwitterionic molecules on Si(111)-7×7 substrates has been probed by scanning tunneling microscopy and spectroscopy and studied via density-functional-theory calculations. Experimental results obtained at room and low temperatures revealed the reconstruction of Si(111)-7×7 half-cells with molecular constructs accommodating three zwitterions. A structural model for the inscription of the Si(111)-7×7 half-cell with zwitterionic edifices is proposed and the nature of the interactions between the molecular assemblies and the surface is established thanks to joint experimental data and simulations.
