A comparison of a commercial hydrodynamics TCAD solver and Fermi kinetics transport convergence for GaN HEMTs
Ashwin Tunga, Kexin Li, Nicholas C. Miller +3
Various simulations of a GaN HEMT are used to study the behaviors of two different energy-transport models: the Fermi kinetics transport model and a hydrodynamics transport model a…
229 nm UV LEDs using p-type silicon for increased hole injection
Dong Liu, Sang June Cho, Jeongpil Park +10
Ultraviolet (UV) light emission at 229 nm wavelength from diode structures based on AlN/Al0.77Ga0.23N quantum wells and using p-type Si to significantly increase hole injection was…
UVC LEDs on Bulk AlN Substrates Using Silicon Nanomembranes for Efficient Hole Injection
Sang June Cho, Dong Liu, Jung-Hun Seo +12
As UV LEDs are explored at shorter wavelengths (< 280 nm) into the UVC spectral range, the crystalline quality of epitaxial AlGaN films with high Al compositions and inefficient ho…
A Discontinuous Galerkin Time Domain Framework for Periodic Structures Subject To Oblique Excitation
Nicholas C. Miller, Andrew D. Baczewski, John D. Albrecht +1
A nodal Discontinuous Galerkin (DG) method is derived for the analysis of time-domain (TD) scattering from doubly periodic PEC/dielectric structures under oblique interrogation. Fi…
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…
