ABSTRACTImprovements of crystal quality in GaAs/Si heterostructure by solid phase epitaxy (SPE) are described. RBS and TEM measurements indicate that high density defects are located near the GaAs/Si interface after “2-step MBE”. Utilization of post SPE process (amorphization plus regrowth) significantly improve crystal qujali ty at the GaAs/Si interface, although a small stress field is introduced. In addition a new relation between photoluminecence intensity ratio and stress field is established. This provides a useful too] for measuring small stresses remaining in the GaAs/Si hetero-structure.

AbstractHigh dose ion implantation followed by solid phase epitaxy has been investigated for use in the synthesis of defect-free graded alloys of Si1−xGex. Two implanted alloy systems were studied: (i) 200 keV 74Ge into <001> Si to form Si-rich alloys and (ii) 150 keV 29Si into <001> Ge to form Ge-rich alloys. After regrowth by solid phase epitaxy the Ge-rich alloys are strained in tension while the Si-rich alloys are in compression and, as a result, strain relaxation is anticipated above a critical dose. We report that solid phase epitaxy at 550°C following implantation of Si into <001> Ge at an energy of 150 keV allowed the defect-free regrowth of alloys with peak concentrations of 11 ± 2 at. % Si (fluence of 7.7 × l016/cm2). Ge was implanted at 200 keV into <001> Si to a peak concentration of 7 at. % (fluence of 3.6 × l016/cm2) and was regrown without the introduction of defects whereas samples implanted to a peak concentration of 13 at. % (fluence of 5.3 × l016/cm2) contained a high density of stacking faults. These experimental observations are compared to theoretical predictions that are based on the strain energy approach.

ABSTRACTIon implantation of Ti into LINbO3 has been shown to be an effective means of producing optical waveguides, while maintaining better control over the resulting concentration profile of the dopant than can be achieved by in-diffusion. While undoped, amorphous LiNbO3 can be regrown by solid-phase epitaxy at 400°C with a regrowth velocity of 250 Å/min, the higher concentrations of Ti required to form a waveguide (∼10%) slow the regrowth considerably, so that temperatures approaching 800°C are used. Complete removal of residual damage requires annealing temperatures of 1000°C, not significantly lower than those used with in-diffusion. Solid phase epitaxy of Agimplanted LiNbO3, however, occurs at much lower temperatures. The regrowth is completed at 400°C, and annealing of all residual damage occurs at or below 800°C. Furthermore, the regrowth rate is independent of Ag concentration up to the highest dose implanted to date, 1 × 1017 Ag/cm2. The usefulness of Ag implantation for the formation of optical waveguides is limited, however, by the higher mobility of Ag at the annealing temperature, compared to Ti.
