    Controlled polytypic and twin-plane superlattices in iii–v nanowires

    Semiconductor nanowires show promise for use in nanoelectronics, fundamental electron transport studies, quantum optics and biological sensing. Such applications require a high degree of nanowire growth contro...

    Structural Characterisation of GaP <111>B Nanowires by HRTEM

    GaP <111>B nanowires are dominated by (111) twins orthogonal to the growth direction and show well-developed {111} side-facets. Based on this, a 3D-model has been constructed with a cross-section of an octahed...

    Compaction of agglomerates of aerosol nanoparticles: A compilation of experimental data

    The compacting behavior of agglomerated aerosol nanoparticles in the size range between 7 and 150 nm was investigated using available literature data. We observed a characteristic behavior, which can be descri...

    Direct Observation of the Molten State of Nanometer-sized Particles With an Atomic Force Microscope: A Feasibility Study

    An atomic force microscope (AFM) was used to directly examine the physical state of nanometer-sized particles. The critical diameter of indium particles, where evidence of melting at room temperature was obser...

    Characterization of InP/GaInAs Nanometer Sized Columns Produced by Aerosol Deposition and Plasma Etching

    We present a technique for the fabrication of InP nano-columns and GaInAs/InP quantum-dots based on the use of sintered aerosol Ag particles as a mask in an electron cyclotron resonance etching process. The si...
