| Abstract: | A brief review is given to the present status and prospect for atomic layer epitaxy(ALE) technique. The crystal growth procedure and the experimental setup, the kinetic model and the reaction mechanism of GaAs-ALE are reported. The structure and the composition of GaAs films were investigated by means of laser Raman spectroscopy and mass spectroscopy. The in-situ monitoring of the growth process is important in controlling the growth rate as well as in achieving a selective area growth and patterned crystal growth. The experimental results indicate that the crystal epitaxial growth of ultra thin films(atomic size orders) can be realized and GaAs GaAlAs quantum well structure devices have been successfully developed using ALE technique. |
