Strain-induced change of surface reconstructions for InAs„001..
نویسنده
چکیده
The effect of strain on the stability of different surface reconstructions on InAs~001! is investigated with density-functional theory calculations. The effects of isotropic as well as anisotropic tensile and compressive strain is investigated, and the results are presented in corresponding equilibrium phase diagrams. I find that the range of stability for any of the relevant reconstructions can be changed significantly, and, in fact, a reconstruction that is unstable in an unstrained system might be stabilized upon application of external strain.

Surface reconstructions for InAs„001... studied with density-functional theory and STM
The stability of different surface reconstructions on InAs~001! is investigated theoretically and experimentally. Density-functional theory calculations predict four different surface reconstructions to be stable at different chemical potentials. The two dominant reconstructions are the b2 ~234! for high As, and the a2 ~234! for low As overpressure. This trend is confirmed by scanning tunneling...
متن کاملIn situ threshold photoemission yields correlated to surface reconstructions of InAs „001..
Threshold photoemission yields for As and In terminated reconstructions of InAs ~001! are measured in situ and the variation of the photoyield is correlated with the surface stoichiometry. A significant excess in the measured photoelectron yield is found for the In terminated surfaces. These results are compared to a semiempirical model based on density-functional theory calculations of the sur...
متن کاملSurface phases of GaAs and InAs „001... found in the metalorganic vapor-phase epitaxy environment
We have characterized the ~234! and ~432! reconstructions of GaAs and InAs ~001! that are present in a metalorganic vapor-phase epitaxy ~MOVPE! reactor. Scanning tunneling micrographs show that these surfaces are terminated with arsenic and gallium ~or indium! dimers. The ~234! dimer row exhibits a mottled appearance, which is ascribed to the adsorption of alkyl groups on some of the sites. On ...
متن کاملSubsurface dimerization in III-V semiconductor (001) surfaces.
We present the atomic structure of the c(8 x 2) reconstructions of InSb-, InAs-, and GaAs-(001) surfaces as determined by surface x-ray diffraction using direct methods. Contrary to common belief, group III dimers are not prominent on the surface, instead subsurface dimerization of group III atoms takes place in the second bilayer, accompanied by a major rearrangement of the surface atoms above...
متن کاملStrain field of InAs QDs on GaAs (001) substrate surface: characterization by synchrotron X-ray Renninger scanning
Precise lattice parameter measurements in single crystals are achievable, in principle, by X-ray multiple diffraction (MD) experiments. Tiny sample misalignments can compromise systematic usage of MD in studies where accuracy is an important issue. In this work, theoretical treatment and experimental methods for correcting residual misalignment errors are presented and applied to probe the indu...
