Visualization of the local dipole moment at the Si(111) surface using DFT calculations

Abstract A method to simulate the dipole moment mode of the scanning nonlinear dielectric microscope (SNDM) has been developed. This method has been applied to the so-called $${\rm Si(111)-(7 \times 7)}$$ dimer-adatom-stacking-fault (DAS) structure and a $${\rm Si(111)-(2\times2)}$$ surface with one...
