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…
Epitaxial lattice-matched AlScN/GaN distributed Bragg reflectors
Len van Deurzen, Thai-Son Nguyen, Joseph Casamento +2
We demonstrate epitaxial lattice-matched AlScN/GaN ten and twenty period distributed Bragg reflectors (DBRs) grown on c-plane bulk n-type GaN substrates by plasma…
Optical Dipole Structure and Orientation of GaN Defect Single-Photon Emitters
Yifei Geng, Debdeep Jena, Gregory D. Fuchs +2
GaN has recently been shown to host bright, photostable, defect single photon emitters in the 600-700 nm wavelength range that are promising for quantum applications. The nature an…
Excitonic and deep-level emission from N- and Al-polar homoepitaxial AlN grown by molecular beam epitaxy
Len van Deurzen, Jashan Singhal, Jimy Encomendero +8
Using low-temperature cathodoluminescence spectroscopy, we study the properties of N- and Al-polar AlN layers grown by molecular beam epitaxy on bulk AlN{0001}. Compared to the bul…
Defeating Broken Symmetry with Doping: Symmetric Resonant Tunneling in Noncentrosymetric Heterostructures
Jimy Encomendero, Vladimir Protasenko, Debdeep Jena +1
Resonant tunneling transport in polar heterostructures is intimately connected to the polarization fields emerging from the geometric Berry-phase. In these structures, quantum conf…
Fighting Broken Symmetry with Doping: Toward Polar Resonant Tunneling Diodes with Symmetric Characteristics
Jimy Encomendero, Vladimir Protasenko, Farhan Rana +2
The recent demonstration of resonant tunneling transport in nitride semiconductors has led to an invigorated effort to harness this quantum transport regime for practical applicati…
