Surface-dimer and bulk-atom imaging of the Si(001) (2x1) surface by Kikuchi electron holography.
Physical Review B. 52, 16884-16891., Dec, Number 23
AbstractDirect inversion of measured multiple-energy Kikuchi electron patterns from a Si(001) (2 x 1) surface with glancing and normal-incidence geometry shows clear images of the surface dimer and the bulk atoms. The three-dimensional artifact-free real-space images of the atoms contributed from different local emitters are resolved clearly. The observations demonstrate that Kikuchi electron holography has the surface sensitivity and can reveal the atomic structures of complicated multiemitter systems. By changing the collecting angle of Kikuchi electrons, one can selectively image the atoms behind the emitter in the backward direction; thus the surface and the bulk information can be obtained with different collecting angles. Therefore, the potential of Kikuchi electron holography to solve the local atomic structure of the unknown surfaces is high.

SURFACE DIMER IMAGING USING KIKUCHI ELECTRON HOLOGRAPHY - A STUDY ON SI(001)(2X1) SURFACE.
Surface Science. 312, L743-L747., Jun, Number 1-2
AbstractWe obtained highly resolved and artifact-free 3D holographic images reconstructed from measured Kikuchi electron (quasi-elastic electron) diffraction patterns with contributions from different emitters. Direct inversion of Kikuchi patterns with glancing incidence geometry shows clear images of the surface dimer and the bulk atoms of Si(001)(2 x 1) surface. This observation demonstrates the applicability of electron-emission holography to complicated systems that contain more than one emitter. This work also demonstrates the surface sensitivity of Kikuchi electron holography.
