A Composite Phononic Crystal Design for Quasiparticle Lifetime Enhancement in Kinetic Inductance Detectors
Tuomas A. Puurtinen, Karwan Rostem, Pieter J. de Visser +1
A nanoscale phononic crystal filter (reflector) is designed for a kinetic inductance detector where the reflection band is matched to the quasiparticle recombination phonons with t…
Simultaneous Noise and Impedance Fitting to Transition-Edge Sensor Data using Differential Evolution
Ari Pekka Helenius, Tuomas Puurtinen, Kimmo Kinnunen +1
We discuss a robust method to simultaneously fit a complex model both to the complex impedance and the noise data for transition-edge sensors (TES). It is based on a differential e…
Minimizing coherent thermal conductance by controlling the periodicity of two-dimensional phononic crystals
Yaolan Tian, Tuomas A. Puurtinen, Zhuoran Geng +1
Periodic hole array phononic crystals (PnC) can strongly modify the phonon dispersion relations, and have been shown to influence thermal conductance coherently, especially at low…
