Energy levels in polarization superlattices: a comparison of continuum strain models
B. Jogai, J. D. Albrecht, E. Pan
A theoretical model for the energy levels in polarization superlattices is presented. The model includes the effect of strain on the local polarization-induced electric fields and…

Electromechanical coupling in free-standing AlGaN/GaN planar structures
B. Jogai, J. D. Albrecht, E. Pan
The strain and electric fields present in free-standing AlGaN/GaN slabs are examined theoretically within the framework of fully-coupled continuum elastic and dielectric models. Si…

The effect of electromechanical coupling on the strain in AlGaN/GaN heterojunction field effect transistors
B. Jogai, J. D. Albrecht, E. Pan
The strain in AlGaN/GaN heterojunction field-effect transistors (HFETs) is examined theoretically in the context of the fully-coupled equation of state for piezoelectric materials.…
