Leveraging both faces of polar semiconductor wafers for functional devices
Len van Deurzen, Eungkyun Kim, Naomi Pieczulewski +8
Unlike non-polar semiconductors such as silicon, the broken inversion symmetry of the wide bandgap semiconductor gallium nitride leads to a large electronic polarization along a un…

Ultrawide bandgap semiconductor heterojunction p-n diodes with distributed polarization doped p-type AlGaN layers on bulk AlN substrates
Shivali Agrawal, Len van Deurzen, Jimy Encomendero +7
Ultrawide bandgap heterojunction p-n diodes with polarization-induced AlGaN p-type layers are demonstrated using plasma-assisted molecular beam epitaxy on bulk AlN substrates. Curr…
