Bravais lattice diversity of III-V semiconductors: A comparative study of GaSb(001) and GaAs(001) surface reconstructions
Lattice distortion of the (4x3) reconstruction family of GaSb(001) is compared to the GaAs(001) beta-(2x4) and c(4x4) reconstructions. Low energy differences would allow for the existence of phase shifted reconstruction reg...

Ab initio study of one-dimensional disorder on III-V semiconductor surfaces
Atomic disorder on GaSb(001) and GaAs(001) surfaces is studied by ab initio calculations within density functional theory (DFT). Surface energies are computed for GaSb(001)and GaAs(00...

Ab initio study of GaSb(001)-c(2 x 10) and (2 x 10) reconstructions
GaSb(001) surface reconstructions with the experimentally observed (2 x10) and c(2x10) symmetry are investigated employing density functional theory. Special attention is given to the incorporation of Ga atoms during the in...

Stoichiometry and Bravais lattice diversity: an ab initio study of the GaSb(001) surface
We study the family of GaSb(001)-(4x3) reconstructions by ab initio density-functional theory. For each possible surface stoichiometry between the well-known Sb-poor to the beta2(2x4) reconstructed GaAs(001) su...

GaSb(001) surface reconstructions measured at the growth front by furface X-ray diffraction
Surface x-ray diffraction was employed, in situ, to measure the GaSb(001)-(1 x 5) and (1 x 3) surface phases under technologically relevant growth conditions from the superstructure of the surface reconstr...

Staircase model of GaSb(001) (1x3) and c(2x6) phases
We show that the (1x3) and c(2x6) diffraction patterns of the reconstructed GaSb(001) surface are the result of characteristic disorder in the positions of the (4x3) reconstructed surface unit cells. The reconstruc...

Morphological instability in InAs/GaSb superlattices due to interfacial bonds
Synchrotron x-ray diffraction is used to compare the misfit strain and composition in a self-organized nanowire array in an InAs/GaSb superlattice with InSb interfacial bonds to a planar InAs/GaSb superlattice with GaAs interfacial ...
