Narrow-line light emission from porous silicon multilayers and microcavities
Porous silicon multilayers and microcavities, prepared by the pulsed electrochemical etching method, exhibit a variety of reflectivity and photoluminescence spectra. A comparison of the measured results with those calculated based on the transfer matrix method and quantum-box model reveals that the variation of the spectra can be attributed to the change in wavelength position of the stop-band ...
متن کاملElectron emission from porous silicon planar emitters
Porous silicon planar emitters were fabricated by depositing a thin Au film on a conventional porous Si and their emission characteristics were examined. The emission currents and energy distributions were measured for the emitters with various Au thicknesses and for cesiated ones. The experimental results suggest that the emission mechanism of the porous silicon emitter studied in this work is...
متن کاملLight emission in silicon from carbon nanotubes.
The use of optics in microelectronic circuits to overcome the limitation of metallic interconnects is more and more considered as a viable solution. Among future silicon compatible materials, carbon nanotubes are promising candidates thanks to their ability to emit, modulate, and detect light in the wavelength range of silicon transparency. We report the first integration of carbon nanotubes wi...
