Nanoparticles are rapidly becoming ubiquitous in modern technology and so there is an emerging need to characterise single nanoparticles rapidly and accurately. In the current technological paradigm, non-optical techniques such as electron microscopy (EM) and atomic-force microscopy (AFM) are favored for this role. Nano-characterization using optical microscopy though has several advantages; it can...
In the growth of GaAsP nanowires on GaAs (001) substrates, it was found that the P concentrations in the nanowires and unintentional two-dimensional (2D) GaAsP layer are different. Possible explanations are given.
We report the effect of V/III ratio and nanowire diameter on the crystal structure and optical properties of InP nanowires. Time -resolved photoluminescence studies have revealed that wurtzite nanowires show longer carrier lifetimes than zinc-blende ones.
