Quantum Transport in Graphene Using Surface Acoustic Wave Resonators
Yawen Fang, Yang Xu, Kaifei Kang +7
Surface acoustic waves (SAWs) provide a contactless method for measuring the wavevector-dependent conductivity. This technique has been used to discover emergent length scales in t…
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…
Multi-beam RF accelerators for ion implantation
Peter A. Seidl, Arun Persaud, Diego Di Domenico +10
We report on the development of a radio frequency (RF) linear accelerator (linac) for multiple-ion beams that is made from stacks of low cost wafers. The accelerator lattice is com…
Waferscale Electrostatic Quadrupole Array for Multiple Ion Beam Manipulation
K. B. Vinayakumar, A. Persaud, P. A. Seidl +5
We report on the first through-wafer silicon-based Electrostatic Quadrupole Array (ESQA) to focus high energy ion beams. This device is a key enabler for a wafer based accelerator…
