摘要
The amounts of intrinsic carbon incorporation in AlGaAs epilayers grown by metalorganic chemical vapor deposition (MOCVD) were compared between ones grown using AsH3 and ones grown using tertiarybuthylarsine (TBAs). The hole concentration of the epilayers grown using TBAs was much lower than that of the epilayers grown using AsH3. It has been suggested that As-2 and/or As-4 molecules have the ability to remove methyl groups originating from group-III source materials.
