摘要: The growth of the InAs film directly on the Si substrate deflected from the plane (100) at 4° towards (110) has been performed using a two-step procedure. The effect of the growth and annealing temperature on the electron mobility and surface topography has been investigated for a set of samples. The results show that the highest electron mobility is 4640 cm2/V·in the sample, in which the 10-nm InAs nucleation layer is grown at a low temperature of 320℃ followed by ramping up to 560℃, and the nucleation layer was annealed for 15 min and the second layer of InAs is grown at 520℃. The influence of different buffer layers on the electron mobility of the samples has also been investigated, which shows that the highest electron mobility of 9222 cm2/V·at 300 K is obtained in the sample grown on a thick and linearly graded InGaAlAs metamorphic buffer layer deposited at 420℃.
