Kilovolt Pyroelectric Voltage Generation and Electrostatic Actuation With Fluidic Heating
Di Ni, Ved Gund, Landon Ivy +1
Integrated micro power generators are crucial components for micro robotic platforms to demonstrate untethered operation and to achieve autonomy. Current micro robotic electrostati…
Ferroelectric AlBN Films by Molecular Beam Epitaxy
Chandrashekhar Savant, Ved Gund, Kazuki Nomoto +13
We report the properties of molecular beam epitaxy deposited AlBN thin films on a recently developed epitaxial nitride metal electrode Nb2N. While a control AlN thin film exhibits…
FerroHEMTs: High-Current and High-Speed All-Epitaxial AlScN/GaN Ferroelectric Transistors
J. Casamento, K. Nomoto, T. S. Nguyen +11
We report the first observation of ferroelectric gating in AlScN barrier wide-bandgap nitride transistors. These FerroHEMT devices realized by direct epitaxial growth represent a n…
HZO-based FerroNEMS MAC for In-Memory Computing
Shubham Jadhav, Ved Gund, Benyamin Davaji +4
This paper demonstrates a hafnium zirconium oxide (HZO)-based ferroelectric NEMS unimorph as the fundamental building block for very low-energy capacitive readout in-memory computi…
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.…
Ferroelectricity in Polar ScAlN/GaN Epitaxial Semiconductor Heterostructures
Joseph Casamento, Ved Gund, Hyunjea Lee +11
Room temperature ferroelectricity is observed in lattice-matched ~18% ScAlN/GaN heterostructures grown by molecular beam epitaxy on single-crystal GaN substrates. The epitaxial fil…
