3D patterning of silicon by contact etching with anodically biased nanoporous gold electrodes

Encarnación Torralba, Mathieu Halbwax, Taha El Assimi, Marin Fouchier, Vincent Magnin, Joseph Harari, Jean-Pierre Vilcot, Sylvain Le Gall, Raphaël Lachaume, Christine Cachet-Vivier, Stéphane Bastide

A novel strategy to achieve 3D pattern transfer into silicon in a single step without using lithography is presented. Etching is performed electrochemically in HF media by contacting silicon with a positively biased, patterned, metal electrode. Dissolution is localized at the Si/metal contacts and…

Luminescence imaging of photoelectron spin precession during drift in a p-type GaAs microfabricated Hall bar

V. Notot, D. Paget, A. Rowe, L. Martinelli, Fabian Cadiz, S. Arscott

Using a microfabricated p-type GaAs Hall bar, it is shown that the combined application of co-planar electric and magnetic fields enables the observation of spatial oscillations of the photoluminescence circular polarization due to the precession of drifting spin-polarized photoelectrons.…

Experimental investigation of the lateral resolution of a homemade near field microwave microscope

Tianjun Lin, S. Gu, T. Lasri

In this paper an experimental investigation of the lateral resolution of a homemade near field microwave microscope (NFMM) is reported. The optimal lateral resolution is studied by a thorough analysis of the influence of critical parameters such as the stand-off distance, the tip apex size and the…
