Abstract
The composition of MBE-grown GaAs1¿xSbx (x<0.15) is investigated as a function of growth temperature for constant As and Sb flux and as a function of Sb effusion cell temperature for a fixed growth temperature. Under conditions of constant As and Sb flux, x remains fairly constant for growth temperatures of 480¿540°C, but decreases rapidly with increasing temperature in the range 540¿640°C. As a function of Sb effusion cell temperature, the Sb mole fraction is shown to increase slightly slower than the Sb vapour pressure.
