Professional Summary

Dr. Ayers’ research focuses on the growth, modeling, and characterization of mismatched heteroepitaxial semiconductors for device applications. His research group has developed the standard approaches for modeling strain relaxation and dislocation densities in semiconductor heterostructures. These approaches address both the equilibrium configuration and the kinetically-limited relaxation and non-equilibrium defect densities. Other novel work by the research group has extended the x-ray characterization of heterostructures to the metamorphic case, in which the mosaic broadening of threading dislocations must be included.
