Evidence of Smaller 1/F Noise in AlScN-Based Oscillators Compared to AlN-Based Oscillators

Luis Guillermo Villanueva Torrijo, Marco Liffredo, Andrea Lozzi

In this paper we investigate the direct effect of resonator quality factor (Q) on the oscillator phase noise. We use 2-port contour mode resonators (CMRs), fabricated both with aluminum nitride (AlN) and aluminum scandium nitride (AlScN), as the frequency- ...

Shape memory polymer resonators as highly sensitive uncooled infrared detectors

Herbert Shea, Luis Guillermo Villanueva Torrijo, Tom Larsen, Juan José Zarate, Ulas Adiyan

Uncooled infrared detectors have enabled the rapid growth of thermal imaging applications. These detectors are predominantly bolometers, reading out a pixel’s temperature change due to infrared radiation as a resistance change. Another uncooled sensing met ...

Frequency fluctuations in silicon nanoresonators

Luis Guillermo Villanueva Torrijo, Eric Sage, Thomas Alava

Frequency stability is key to the performance of nanoresonators. This stability is thought to reach a limit with the resonator's ability to resolve thermally induced vibrations. Although measurements and predictions of resonator stability usually disregard ...
