Jc. Garcia et al., HIGH-QUALITY 0.98-MU-M GAINAS GAAS/GAINP LASERS GROWN BY CBE USING TERTIARYBUTYLARSINE AND TERTIARYBUTYLPHOSPHINE/, Electronics Letters, 29(5), 1993, pp. 432-433
HIgh quality GaInAs/GaAs/GaInP laser structures were grown by chemical
beam epitaxy using tertiarybutylarsine (TBAs) and tertiarybutylphosph
ine (TBP) under pulsed conditions. For a 300 mum long cavity, a thresh
old current density of 390 A/cm2 and external quantum efficiency of 0.
6 W/A (two facets) were obtained, which are typical for this kind of s
tructure. This demonstrates the suitability of TBP and TBAs as substit
utes of arsine and phosphine in chemical beam epitaxy for laser fabric
ation.
