Silicon carbide thin films for MEMS nanoreactors for in-situ transmission electron microscopy

Artificial Dielectric Layer Based on PECVD Silicon Carbide for Terahertz Sensing Applications

The refractive index of a conventional dielectric layer can be enhanced using an Artificial Dielectric Layer (ADL). Here we present the fabrication of low temperature PECVD Silicon Carbide (SiC) membranes with very high refractive index (up to 5 at 1 THz) in the terahertz frequency range. The SiC deposition parameters have been tuned to reach a...

Tailoring the Mechanical Properties of High-Aspect-Ratio Carbon Nanotube Arrays using Amorphous Silicon Carbide Coatings

The porous nature of carbon nanotube (CNT) arrays allows for the unique opportunity to tailor their mechanical response by the infiltration and deposition of nanoscale conformal coatings. Here, we fabricate novel photo-lithographically defined CNT pillars that are conformally coated with amorphous silicon carbide (a-SiC) to strengthen the...

Conducted EMI in Inverters with SiC Transistors

Conducted EMI in Inverters with SiC Transistors Electromagnetic Interference (EMI) is the main side effect accompanied with the fast voltage and current switching transients in power electronics applications. Compliance of the Electromagnetic Compatibility (EMC) standard is prescribed for any power electronics product before entering the market....

A comparison between PECVD and ALD for the fabrication of slot waveguide based sensors

We fabricated horizontal slot waveguides using two low temperature deposition techniques ensuring the full compatibility of the processes with CMOS technology. Slots width as thin as 45 nm with smooth slot surfaces can easily be fabricated with simple photolithographic steps. Fundamental TM-like slot mode in which the E-field is greatly enhanced...

Demonstration of PECVD SiC thermal delay lines for optical coherence tomography in the visible

Optical Coherence Tomography (OCT) has found applications in many fields of medicine and has a large potential for the optical biopsy of tumors. One of the technological challenges impairing faster adoption of OCT is the relative complexity of the optical instrumentation required, which translates into expensive and bulky setups. In this paper...
