Abstract
Growth of GaInTlAs alloys on InP has been attempted by solid source molecul ar beam epitaxy (MBE). Thallium atoms segregate into droplets on the surfac e at growth temperatures higher than 270 degreesC and evaporate at temperat ures higher than 350 degreesC. Only in the low temperature range (180-270 d egreesC) can thallium be incorporated in some conditions, leading generally to twinned or polycrystalline layers. A narrow window for single-crystalli ne growth has been found for low Tl contents (4%) using optimized growth co nditions. (C) 2001 Elsevier Science B.V. All rights reserved.
