Broken Symmetry Effects due to Polarization on Resonant Tunneling Transport in Double-Barrier Nitride Heterostructures
Jimy Encomendero, Vladimir Protasenko, Berardi Sensale-Rodriguez +4
The phenomenon of resonant tunneling transport through polar double-barrier heterostructures is systematically investigated using a combined experimental and theoretical approach.…
Epitaxial ScAlN on GaN is a High K Dielectric
Joseph Casamento, Hyunjea Lee, Takuya Maeda +7
Epitaxial ScAlN thin films of ~100 nm thickness grown on metal polar GaN exhibit significantly enhanced relative dielectric permittivity () values relative to AlN.…
Optimization methods for achieving high diffraction efficiency with perfect electric conducting gratings
Rubén Aylwin, Gerardo Silva-Oelker, Carlos Jerez-Hanckes +1
This work presents the implementation, numerical examples and experimental convergence study of first- and second-order optimization methods applied to one-dimensional periodic gra…
Level spectrum and charge relaxation in a silicon double quantum dot probed by dual-gate reflectometry
Alessandro Crippa, Romain Maurand, Dharmraj Kotekar-Patil +10
We report on dual-gate reflectometry in a metal-oxide-semiconductor double-gate silicon transistor operating at low temperature as a double quantum dot device. The reflectometry se…
Repeatable Room Temperature Negative Differential Conductance in GaN/AlN Resonant Tunneling Diodes
Jimy Encomendero, Faiza Afroz Faria, S. M. Islam +5
Double barrier GaN/AlN resonant tunneling heterostructures have been grown by molecular beam epitaxy on the (0001) plane of commercially available bulk GaN substrates. Resonant tun…
Polarization-induced Zener Tunnel Diodes in GaN/InGaN/GaN Heterojunctions
Xiaodong Yan, Wenjun Li, S. M. Islam +4
By the insertion of thin InGaN layers into Nitrogen-polar GaN p-n junctions, polarization-induced Zener tunnel junctions are studied. The reverse-bias interband Zener tunneling cur…
