Optofluidic notch filter integration by lift-off of thin films
Optofluidic platforms used for biomolecular detection require spectral filtering for distinguishing analyte signals from unwanted background. Towards a fully integrated platform, an on-chip filter is required. Selective deposition of dielectric thin films on an optofluidic sensor based on antiresonant reflecting optical waveguide (ARROW) technology provides the means for localized, on-chip opti...
متن کاملTransport Properties of Epitaxial Lift Off Films
Transport properties of epitaxially lifted-off (ELO) films were characterized using conductivity, Hall and Shubnikov-de Haas measurements. A 10-15% increase in the 2D electron gas concentration was observed in these films as compared with adjacent conventional samples. We believe this result to be caused by a backgating effect produced by a charge build up at the interface of the ELO film and t...
متن کاملSELECTIVE UV-LASER PROCESSING FOR LIFT-OFF OF GaN THIN FILMS FROM SAPPHIRE SUBSTRATES
Gallium nitride (GaN) thin films on sapphire substrates were successfully separated and transferred onto Si substrates by pulsed UVlaser processing. A single 600 mJ/cm, 38 ns KrF excimer laser pulse was directed through the transparent substrate to induce a rapid thermal decomposition of the GaN at the GaN/sapphire interface. The decomposition yields metallic Ga and N2 gas that allows separatio...
متن کاملLift-off protocols for thin films for use in EXAFS experiments.
Lift-off protocols for thin films for improved extended X-ray absorption fine structure (EXAFS) measurements are presented. Using wet chemical etching of the substrate or the interlayer between the thin film and the substrate, stand-alone high-quality micrometer-thin films are obtained. Protocols for the single-crystalline semiconductors GeSi, InGaAs, InGaP, InP and GaAs, the amorphous semicond...
