Abstract
The P-rich (2×1)/(2×2) and the In-rich (2×4) reconstructions of InP(001) are studied by Angle Resolved Photoemission Spectroscopy (ARPES). Experimental results for the In-rich (2×4) InP(001) surface show two bound surface states and one surface resonance, located at −1.6 eV binding energy. This agrees well with ab-initio calculations. For the P-rich (2×1)/(2×2) InP(001) surface, neither theoretical nor experimental work regarding the electronic surface structure exists until now. We identify two possible surface states showing no discernible dispersion along the Γ̄– J̄ and Γ̄– J̄′ directions of the surface Brillouin zone (SBZ). The energetically highest state, located close to the valence band maximum (VBM), is only observed along the [1̄10] direction and is most likely a P-dimer-bond state. The second state, located at −4.4 eV binding energy, is assigned to a surface resonance.
