Studies of LaA103{100} surfaces using RHEED and REM II: 5 X 5 surface reconstruction
For the first time, 5 X 5 surface reconstruction on annealed LaAIO3{100} surfaces is observed with reflection high-energy electron diffraction (RHEED) and reflection electron microscopy (REM). Most of the {100} surface areas are covered by the reconstructed layer. The presence of twin boundaries and protrusion contaminants on the surface has no influence on the formation of the reconstruction. ...
متن کاملTime-resolved RHEED Studies of the Growth of Epitaxial ZnSe Films on GaAs By Pulsed Laser Deposition
Film growth consists of two basic processes, deposition and surface relaxation, with opposing effects on the evolution of surface roughness. The pulsed-laser deposition (PLD) growth process has the unique feature of having periods of very high deposition rates on μs time scales followed by periods, on the order of seconds, with only surface relaxation. In this paper we report the first efforts ...
متن کاملSURFACE ACOUSTIC WAVE STUDIES OF DEFECTS IN ELECTRON IRRADIATED GaAs
Surface Acoustic Waves (SAW) provide a means of studying low temperature anelastic relaxations of crystal defects produced by irradiation. Due to their confinement near the surface where radiation induced defect concentrations are highest. SAW are more sensitive than bulk ultrasonic waves in these investigations. Furthermore. for piezoelectric materials. the use of photolithographically deposit...
متن کاملReliable synthesis of self-running Ga droplets on GaAs (001) in MBE using RHEED patterns
Self-running Ga droplets on GaAs (001) surfaces are repeatedly and reliably formed in a molecular beam epitaxial (MBE) chamber despite the lack of real-time imaging capability of a low-energy electron microscope (LEEM) which has so far dominated the syntheses and studies of the running droplets phenomenon. Key to repeatability is the observation and registration of an appropriate reference poin...
متن کاملLarge scale surface structure formed during GaAs (001) homoepitaxy
Atomic force microscopy studies have been performed on GaAs (001) homoepitaxy Rlrns grown by molecular beam epitaxy. Multilayered features are seen to evolve when the growth conditions favor island nucleation. As the epilayer thickness is increased these features grow in all dimensions but the angle of inclination remains approximately constant at 1”. The mounding does not occur on surfaces gro...
