A Scanning Near-field Photon Emission Microscope (SNPEM) for monitoring photon emission sites with a spatial resolution of between 50 to 200 nm is described. A protrusion type probe with a base diameter larger than a wavelength is proposed as a good compromise between resolution and sensitivity. Photon emissions from silicon pn junction and n-MOSFET have been detected with resolution clearly better...
For the first time embossing of ribs, from 1 to 10μm wide and ∼10mm long, has been carried out in chalcogenide glass layers sputtered onto semiconductor wafer substrates, with potential to act as monomode waveguides; these features have been similarly embossed in the surface of bulk chalcogenide glasses. The embossing shows very good replication of the GaAs mould patterning to 1μm definition, with...
