Photonic Crystal Nanocavities for Efficient Light Confinement and Emission
When combined with high index contrast slabs in which light can be efficiently guided, microfabricated two-dimensional photonic crystals provide us with the geometries needed to confine and concentrate light into extremely small volumes and to obtain very high field intensities. Fabrication of optical structures has now evolved to a precision which allows us to control light within such etched ...
متن کاملMicrofabricated drug delivery devices.
We review newest developments in the design and fabrication of drug delivery devices based on micropatterned structures. Electronic devices have now reached a stage of dimensions comparable to those of biological macromolecules. This raises exciting possibilities for combining microelectronics and biotechnology to develop new technologies with unprecedented power and versatility. While molecula...
متن کامل“Playing around” with Field-Effect Sensors on the Basis of EIS Structures, LAPS and ISFETs
Microfabricated semiconductor devices are becoming increasingly relevant, also for the detection of biological and chemical quantities. Especially, the “marriage” of biomolecules and silicon technology often yields successful new sensor concepts. The fabrication techniques of such silicon-based chemical sensors and biosensors, respectively, will have a distinct impact in different fields of app...
متن کاملFabrication of gated cathode structures using an in situ grown vertically aligned carbon nanofiber as a field emission element
Vertically aligned carbon nanofibers ~VACNFs! are extremely promising cathode materials for microfabricated field emission devices, due to their low threshold field to initiate electron emission, inherent stability, and ruggedness, and relative ease of fabrication at moderate growth temperatures. We report on a process for fabricating gated cathode structures that uses a single in situ grown ca...
متن کاملMultimode Emissions from MEH-PPV Blended with Polystyrene Film Waveguides
In the context of conjugated polymers, especially those of the poly (phenylenevinylene) (PPV) family, which are promising candidates as emission material in light emitting devices such as LEDs, field effect transistors and photovoltaic devices, we have, in the present study, prepared MEH-PPV [Poly [2- methoxy-5-(2’-ethyl-hexyloxy)-1,4-phenylen-evinylene] of low molecular weight and low polydisp...
