Abstract
Single-domain Si(100) 2 × 1 and Si(100):As 1 × 2 surfaces have been obtained by using samples cut at 4° from the (100) crystal axis with the tilt towards [011]. Low-energy electron diffraction results show that steps on the surface are predominantly two atomic layers high. The ordering on the terraces is good and has allowed us to obtain surface-state dispersions with angle-resolved photoemission for clean and As-terminated single-domain Si(100) 2 × 1 surfaces.Keywords
