Lin H.-Y.G., Lin P-T, Lin H.-Y.G., Lin P-T, Singh V., Patel N.S., Hu J., Richardson K., Luzinov I., Hensley J., Kimerling L., Murthy Agarwal A., Massachusetts Institute of Technology, US

Mid-Infrared optofluidics based silicon sensor platforms are demonstrated. Silicon is a great candidate for mid-infrared optofluidics for the following reasons: (1) Silicon has a broad transmission window up to 7 um (2) Silicon offers CMOS [...]

Structural Color Generation in Silicon Nanowires Enable Low-Cost Refractive Index Sensors

Walia J., Khorasaninejad M., Dhindsa N., Saini S.S., University of Waterloo, CA

Structural colors are generated using waveguiding and diffractive effects in ordered silicon nanowire arrays. Tunable colors can be achieved by changing the angle of incidence. The generated colors are used for refractive index sensors with [...]

Putting The World In A Spin – Fibercore’s Spun Optical Fibers For The Current Sensor Industry

Gillooly A., Fibercore Limited, UK

The development and growth of spun optical fibers for Faraday effect current sensors is a perfect example of how having a killer technology also requires a killer application. Spun fibers have sat in the shadows [...]

Photoconductivity of Reduced Graphene Films

Loomis J., Panchapakesan B., University of Louisville, US

In this paper, we report large photocurrents in air-assisted depositions of reduced graphene films (derived from reduced single layer graphene oxide) upon illumination with near-infrared (NIR) light. NIR-induced charge carrier generation and subsequent separation at [...]

Nanoelectronics is a very promising step the world of electronics is taking. It is proved to be more efficient than the microelectronic approaches currently in use, mainly in terms of area and energy management. A [...]

Surface Passivation of GaAs Nanowires Ensembles for Photovoltaic Applications

Chia A.C.E., LaPierre R.R., McMaster University, CA

Fabrication, electrical characterization and analytical modeling of an AlInP-passivated GaAs NW ensemble is presented. Novel processing steps were used to fabricate NW ensemble devices which were subsequently characterized electrically and fit with an analytical model, [...]

Electro-thermal aspects in carbon based interconnects

Verma R., Bhattacharya S., Mahapatra S., Indian Institute of Science, IN

The tremendous rise in Joule-heating in conventional ICs has led down ITRS to ensure on material alternatives that surpasses break-down current density and thermal conductivity (κ) beyond room temperature (RT). In recent years, suspended metallic [...]
