A technique for the fabrication of colloidal gold nano-wire and nano-dumbbell shaped particles using rod shaped viruses as templates is described. The gold (Au) encapsulation process was accomplished by the precipitation of gold chloride from aqueous

Colloidal silica spheres with 290 nm diameters were self-assembled with single crystal crystallites 4–5 mm wide and 10–15 mm long. Larger spheres with diameters between 1000 and 2300 nm were self-assembled with single crystal crystallites up to 1

We present results from photoreflectance (PR) experiments conducted near the E 1 transition energies (2.60–3.35 eV) of Al0.25Ga0.75As/In0.15Ga0.85As heterostructures that constitute the upper layers of pseudomorphic high electron mobility transisto

We have observed the behavior of photoreflectance (PR) spectra from a set of a molecular-beam-epitaxy-grown heterostructures as a function of the modulation duty cycle. This was done over a range of frequencies extending from 101000 Hz. By varying

The E1 and E1+Δ1 energy bands of metal–organic chemical vapor deposition grown AlxGa1−xAs, with x in the range 0–0.55, have been determined using photoreflectance technique. The aluminum composition for each sample was determined using the ene

Photoreflectance spectra were obtained from an epitaxial film and a bulk single crystal of β-FeSi2 at low temperatures (T⩽180 K). A model based on the results of low-temperature absorption [M. Rebien et al., Appl. Phys. Lett. 74, 970 (1999)] was u

Inverse gold photonic crystals templated from synthetic opals with a face centered cubic (FCC) crystal lattice were constructed by heat converting gold chloride to metallic gold. Tetrahedral formations constructed of alternating large and small octah

The photoreflectance spectra of ion beam synthesized β-FeSi2 reveals a direct gap at 0.815 eV and are shown to agree with the band gap value obtained by photoluminescence once the adjustments for the temperature difference and trap related recombina

Photoreflectance (PR), a contactless form of electromodulation, is used in a study of the In1−xGaxSb alloy series. The samples consist of epilayers of In1−xGaxSb (0.780⩽x⩽0.900) grown by molecular beam epitaxy onto (100) GaSb substrates, resu

The photoreflectance (PR) spectra of MOCVD grown Zn:AlxGa1-xAs with 0 < x < 0.55 and carrier concentration, N, of ~ 5 × 1017 to ~ 1 × 1019 cm-3 was studied at the E1 transition energy. Of particular interest was the effect of varying N and x on E1,
