title = "Digital alloy InGaAs/InAlAs laser structures studied by cross-sectional scanning tunneling microscopy",
abstract = "We have studied digital alloy InAlAs/InGaAs quantum well and quantum cascade laser structures with cross-sectional scanning tunneling microscopy.We show the effect of rapid thermal annealing on structural properties of a digital alloy quantum well structure. Further, we compare a quantum cascade laser structure with digital alloy graded barriers to a structure with abrupt interfaces. We show that due to alloy fluctations, softening of the barriers occurs even without the digital alloy grading.",
