ABSTRACT
Crystalline and amorphous GaSb surfaces are compared concerning their response to sputter erosion with low energy Ar[sup +] ions under normal incidence. We show that the formation of regular nanostructures on GaSb is basically independent of whether the initial material is crystalline or amorphous. The similarity in the temporal and spatial evolution demonstrates that the dynamics of the morphology evolution is entirely controlled by a thin amorphous surface layer.

    Nitrogen-doped gallium phosphide nanobelts were directly synthesized via a sublimation of ball-milled powders under ammonia flow. The average width of the nanobelts is 300 nm and the thickness is about 1/10 of the width. They consist of single-crystalline zinc blende structure crystal with the...

    The epitaxial growth of GaN by Plasma Assisted Molecular Beam Epitaxy was investigated by Scanning Tunnelling Microscope (STM). The GaN film was grown on initial GaN (0001) and monitored by in situ Reflection High Energy Electron Diffraction and STM during the growth. The STM characterization...

    A new method of forming InGaN/GaN nanostructures emitting in the long-wavelength green spectral range is proposed and implemented. The method is based on growing a thin InGaN layer over nanosized pits formed in situ by etching a locally AlN-masked GaN layer in a hydrogen-containing atmosphere.

    The high thermal conductivity and wide bandgap of gallium nitride (GaN) are desirable characteristics in optoelectronics and sensing applications. In comparison to thin films and powders, in the nanofiber morphology the sensitivity of GaN is expected to increase as the exposed area (proportional...
