ABSTRACT
GaAs was selectively grown on GaAs substrates patterned with SiO2 by conventional molecular beam epitaxy (MBE). No growth was found on SiO2, except for small GaAs particles, when the substrate temperature was above 700 °C under 1.2×10-5 Torr arsenic pressure. With the increase in the substrate temperature, the selectivity was better while the growth rate decreased. At 775 °C, no growth occurred, even on GaAs. Selective epitaxial growth of GaAs by MBE is promising for application to device fabrications.
