Query: Tip artifact in atomic force microscopy observations of InAs quantum
  dots grown in Stranski-Krastanow mode   The tip artifact in atomic force microscopy (AFM) observations of InAs
islands was evaluated quantitatively. The islands were grown in the
Stranski-Krastanow mode of molecular beam epitaxy. The width and height of the
islands were determined using transmission electron microscopy (TEM) and AFM.
The average $[\bar{1}10]$ in-plane width and height determined using TEM
excluding native oxide were 22 and 7 nm, respectively; those determined using
AFM including the oxide were 35 and 8 nm, respectively. The difference in width
was due to the oxide and the tip artifact. The sizes including the oxide were
deduced from TEM observations to be a width of 27 nm and a height of 6 nm with
correction for the thickness of the oxide. The residual difference of 8 nm
between the width determined using AFM and that determined using TEM including
the oxide was ascribed to the tip artifact. The results enable us to determine
the actual size of the islands from their AFM images.
