This work analyses the Bi incorporation in InAs<inf>1-x</inf>Bi<inf>x</inf>/InAs(100) epilayers grown by MBE through advanced transmission electron microscopy techniques. Samples grown from 350--400 °C resulted in Bi contents {<}3.3% exhibiting compositional variation in the growth direction. In contrast, roughly spherical clusters appeared in the sample grown at lower temperatures. The clusters are made up of the binary InBi with a tetragonal PbO phase surrounded by a matrix of InAs<inf>0.95</inf>Bi<inf>0.05</inf>indicating the Bi solubility limit in InAs. These InBi crystals underwent a cubic distortion and are tilted 55° with regard to the InAsBi matrix. The crystallographic relationships are analysed in detail.
