TED, TEM and AFM studies comparing atomic ordering in InAsySb1-y layers grown by MOVPE and MBE
CuPt-type atomic ordering in InAsySb1-y layers grown by molecular beam epitaxy (MBE) and metal organic vapour phase epitaxy (MOVPE) on (001) substrates was investigated using TED and TEM. The degree of ordering was greater and occurred at higher temperatures, and the ordered domains were larger, in...

| description | CuPt-type atomic ordering in InAsySb1-y layers grown by molecular beam epitaxy (MBE) and metal organic vapour phase epitaxy (MOVPE) on (001) substrates was investigated using TED and TEM. The degree of ordering was greater and occurred at higher temperatures, and the ordered domains were larger, in the MOVPE layers compared with the MBE layers. AFM showed surface ridges along the [110] direction for the MOVPE layers and along the [<(1)over bar 10>] direction for the M-BE layers. We suggest mechanisms to explain why the differences in ordering for the MOVPE and MBE layers occur. |
