Abstract

2π steradian (full hemisphere) In 3d photoelectron patterns from InP(001) surface were measured. The circular dichroism of rotational shift around the incident-light axis was observed. The forward focusing peaks (FFPs) at [111] and [-1-11] directions were intense, while the FFPs at [-111] and [1-11] directions were weak. This is because the distance to the scatterer atoms at the former directions are one third of that at the latter directions. Rotational shifts of the FFPs at [111] and [-1-11] directions were large, while the FFPs at [-111] and [1-11] directions were small. These shifts correspond to the parallax in the stereograph of the atomic arrangements of zinc blende structure seen from an In atom. [DOI: 10.1380/ejssnt.2009.181]
