Large tunable bandgaps in the InAs/AlAs strain-compensated short-period superlattices grown by molecular beam epitaxy

To explore the bandgap tunability in strain-compensated superlattices, we have grown a series of InAs/AlAs strain-compensated short-period superlattices (SPSs) with different period lengths by molecular beam epitaxy. Although the average indium composition of the InAs/AlAs SPS samples remains the sa...
