Thermal Properties of Nanocrystalline Silicon Nanobeams [PDF]
Advanced Functional Materials, 2021 AbstractControlling thermal energy transfer at the nanoscale and thermal properties has become critically important in many applications since it often limits device performance. In this study, the effects on thermal conductivity arising from the nanoscale structure of free‐standing nanocrystalline silicon films and the increasing surface‐to‐volume ...

Operating Nanobeams in a Quantum Fluid [PDF]
Scientific Reports, 2017 AbstractMicroelectromechanical (MEMS) and nanoelectromechanical systems (NEMS) are ideal candidates for exploring quantum fluids, since they can be manufactured reproducibly, cover the frequency range from hundreds of kilohertz up to gigahertz and usually have very low power dissipation. Their small size offers the possibility of probing the superfluid

Single-Crystal Diamond Nanobeam Waveguide Optomechanics [PDF]
Physical Review X, 2015 Optomechanical devices sensitively transduce and actuate motion of nanomechanical structures using light. Single--crystal diamond promises to improve the performance of optomechanical devices, while also providing opportunities to interface nanomechanics with diamond color center spins and related quantum technologies.

Photonic crystal nanobeam lasers [PDF]
Conference on Lasers and Electro-Optics 2010, 2010 Photonic crystal lasers operating at room temperature based on high Q/V nanobeam cavities have been demonstrated. We reported a large spontaneous emission factor (β∼0.97) by fitting the L-L curve with the rate equations.

Nanobeam photonic bandedge lasers
Optics Express, 2011 We demonstrate one-dimensional nanobeam photonic bandedge lasers with InGaAsP quantum wells at room temperature from the lowest dielectric band of photonic crystal nanobeam waveguides. The incident optical power at threshold is 0.6 mW (effectively ~18 μW).

Si3N4 nanobeam optomechanical crystals [PDF]
CLEO: 2013, 2013 We demonstrate sideband-resolved Si 3 N 4 optomechanical crystals supporting 105 quality factor optical modes at 980 nm, coupled to GHz frequency mechanical modes. We also develop slot-mode-based geometries for enhanced optomechanical coupling and multimode applications.
