Cathodoluminescence spectroscopy on lamellar metal and semiconductor gratings for nano-photonic devices


Cathodoluminescence spectra of lamellar gratings have Gaussian profiles centered at ~600 nm independent of grating amplitude (0.1 to 4.6 microns), grating period (0.1 to 20 microns), material (metal, semimetal, or semiconductor), or e-beam energy, but the band blue-shifts somewhat with increasing e-beam current. A periodic modulation with wavelength appears… (More)
