Low two-level-system noise in hydrogenated amorphous silicon
Fabien Defrance, Andrew D. Beyer, Jordan Wheeler +2
At sub-Kelvin temperatures, two-level systems (TLS) present in amorphous dielectrics source a permittivity noise, degrading the performance of a wide range of devices using superco…

Flat silicon gradient index lens with deep reactive-ion-etched 3-layer anti-reflection structure for millimeter and submillimeter wavelengths
Fabien Defrance, Cecile Jung-Kubiak, John Gill +5
We present the design, fabrication, and characterization of a 100 mm diameter, flat, gradient-index (GRIN) lens fabricated with high-resistivity silicon, combined with a three-laye…
