Description

The alloy phase separation effect in InAlAs spacer layer of InAs/InAlAs nanostructure superlattices was studied by two-dimensional finite element calculation. The calculation results showed that InAs islands with wide top would prefer to induce "V"-like In-rich InAlAs arms above InAs islands in InAlAs spacer layer, while InAs islands with narrow top would promote the formation of "I"-like In-rich InAlAs arms above InAs islands in InAlAs spacer layer which corresponded well with the experimental...[Show more]
