Abstract In this work we analyze GISAXS measurements of the structure factor of Si surfaces evolving during 1 keV Ar+ ion bombardment. Using newly-developed methods sensitive to the full range of experimentally-available wavenumbers q, we extract the

We report an approach to build a tunable spectral imaging system operating in the long-wave infrared (λ=8-12 μm). In addition to broadband images, the imaging systems allows for tunable selection of particular passbands. The tunable passband select

We present measurements of the Faraday effect in n-type InSb. The Verdet coefficient was determined for a range of carrier concentrations near $10^{17}$ $\text{cm}^{-3}$ in the $\lambda$ = 8 $\mu$m - 12 $\mu$m long-wave infrared regime. The absorptio

The Faraday rotation (FR) in Mn-doped InSb (Mn-InSb) depends on extremely low doping of Mn into the InSb lattice. The polycrystalline Mn-InSb was prepared by direct alloying of InSb and Mn2Sb, followed by slow cooling of the melt. X-ray diffraction c

We report the design and operation of a surface-emitting surface acoustic wave (SAW) acousto-optical modulator which behaves as a cm-scale linear hologram in response to an applied electronic waveform. The modulator is formed by an optical waveguide,

Ion beams are frequently used in industry for composition control of semiconducting materials as well as for surface processing and thin films deposition. Under certain conditions, low- and medium energy ions at high fluences can produce nanoripples

We propose and experimentally test a method to fabricate patterns of steep, sharp features on surfaces, by exploiting the nonlinear dynamics of uniformly ion bombarded surfaces. We show via theory, simulation, and experiment, that the steepest parts

A broad class of ``local response'' theories seeks to predict morphology evolution during energetic particle irradiation in terms of average surface height response to individual impacts---an approach that has been generalized by the crater function
