Silicon quantum wire array fabrication by electrochemical and chemical dissolution of wafers

Indirect evidence is presented that free-standing Si quantum wires can be fabricated without the use of epitaxial deposition or lithography. The novel approach uses electrochemi...

Visible light emission due to quantum size effects in highly porous crystalline silicon

Probabilistic Interpretation of Feedforward Classification Network Outputs, with Relationships to Statistical Pattern Recognition

Characterization of silicon avalanche photodiodes for photon correlation measurements 2: Active quenching

We continue examination of the photon correlation properties of silicon avalanche photodiodes operated in photon-counting mode by extending their operation from that of passive ...

1.3-μm light-emitting diode from silicon electron irradiated at its damage threshold

We report 77-K electroluminescence from an irradiated carbon-rich silicon diode that has an internal quantum efficiency more than 103 times higher than that of band-to-band reco...

Non-linear refractive index changes in CdHgTe at 175 K with 10.6μm radiation

Characterization of silicon avalanche photodiodes for photon correlation measurements 3: Sub-Geiger operation

We continue examination of the photon correlation properties of silicon avalanche photodiodes operated in the single-photon counting mode by extending their operation from that ...
