Radiator Tailoring for Enhanced Performance in InAs-Based Near-Field Thermophotovoltaics

Autor: Giroux, Mathieu, Molesky, Sean, St-Gelais, Raphael, Krich, Jacob J.

Near-field thermophotovoltaics (NFTPV) systems have significant potential for waste heat recovery applications, with both high theoretical efficiency and power density, up to 40% and $11 \ \mathrm{W/cm^{2}}$ at 900 K. Yet experimental demonstrations

Vibration Sensitivity of one-port and two-port MEMS microphones

Autor: Doyon-D'Amour, Francis, Stalder, Carly, Hodges, Timothy, Stephan, Michel, Wu, Lixiue, Koukoulas, Triantafillos, Leahy, Stephane, St-Gelais, Raphael

Micro-electro-mechanical system (MEMS) microphones (mics) with two acoustic ports are currently receiving considerable interest, with the promise of achieving higher directional sensitivity compared to traditional one-port architectures. However, mea

Demonstration of Frequency Stability limited by Thermal Fluctuation Noise in Silicon Nitride Nanomechanical Resonators

Autor: Zhang, Chang, St-Gelais, Raphael

The frequency stability of nanomechanical resonators (NMR) dictates the performance level of many state-of-the-art sensors (e.g., mass, force, temperature, radiation) that relate an external physical perturbation to a resonance frequency shift. While

Localized Thermal Gradients On-Chip by Radiative Cooling of Silicon Nitride Nanomechanical Resonators

Autor: Bouchard, Alexandre, Hodges, Timothy, Stephan, Michel, Wu, Lixue, Koukoulas, Triantafillos, Green, Richard, St-Gelais, Raphael

Small scale renewable energy harvesting is an attractive solution to the growing need for power in remote technological applications. For this purpose, localized thermal gradients on-chip--created via radiative cooling--could be exploited to create m
