An Electrically Injected and Solid State Surface Acoustic Wave Phonon Laser
Alexander Wendt, Matthew J. Storey, Michael Miller +6
Surface acoustic waves (SAWs) enable a wide array of technologies including RF filters, chemical and biological sensors, acousto-optic devices, acoustic control of microfluidic flo…
S-band acoustoelectric amplifier utilizing an ultra-high thermal conductivity heterostructure for low self-heating
Lisa Hackett, Xingyu Du, Michael Miller +9
Here we report on an acoustoelectric slab waveguide heterostructure for phonon amplification using a thin AlScN film grown directly on a 4H-SiC substrate with an…
High-Efficiency Three-Wave and Four-Wave Phonon Mixing Via Electron-Mediated Nonlinearity in Semiconductor-Piezoelectric Heterostructures
Lisa Hackett, Matthew Koppa, Brandon Smith +7
We show that phononic frequency conversion can be enhanced by orders of magnitude in piezoelectric systems by heterogeneous integration of high-mobility semiconductor films. A lith…
Nonreciprocal low-noise acoustoelectric microwave amplifiers with net gain in continuous operation
Lisa Hackett, Michael Miller, Scott Weatherred +7
Over sixty years ago, it was hypothesized that specially designed acoustic systems that leveraged the acoustoelectric effect between phonons and charge carriers could revolutionize…
