摘要：
In AlxGa1-xSb crystals grown by the travelling heater method (THM), spatially resolved photoluminescence and cathodoluminescence measurements were carried out at 77 and 20 K, respectively, to detect the AlSb distribution at convective type I and kinetic type II striations (resolution about 4 mum in diameter). The AlSb microscopic segregation effects in the riser area of type II striations can be explained with the non-steady-state step exchange model.
