Faraday cage angled-etching of nanostructures in bulk dielectrics

open access: yes, 2016
For many emerging optoelectronic materials, heteroepitaxial growth techniques do not offer the same high material quality afforded by bulk, single-crystal growth.

Robust charge and magnetic order under electric field and current in the multiferroic LuFe(2)O(4)

open access: yes, 2010
We performed elastic neutron scattering measurements on the charge- and magnetically-ordered multiferroic material LuFe(2)O(4). An external electric field along the [001] direction with strength up to 20 kV/cm applied at low temperature (~100 K) does not

An optical spectroscopic survey of the 3CR sample of radio galaxies with z<0.3. III. Completing the sample

open access: yes, 2010
We present optical nuclear spectra for nine 3CR radio sources obtained with the Telescopio Nazionale Galileo, that complete our spectroscopic observations of the sample up to redshifts $

Laser microprobe facility used in the elemental analysis of small feature of a sample [PDF]

open access: yes, 1969
Laser microprobe facility is effective in the elemental analysis of small areas of heterogeneous samples. The instrument uses the focused beam of a pulsed laser to evaporate a small volume of material from a relatively massive ...

Analysis of broadband microwave conductivity and permittivity measurements of semiconducting materials

open access: yes, 2008
We perform broadband phase sensitive measurements of the reflection coefficient from 45 MHz up to 20 GHz employing a vector network analyzer with a 2.4 mm coaxial sensor which is terminated by the sample under test.
