An optoelectronic device including a semiconductor layer formed from a central segment and at least two lateral segments forming tensioning arms that extend along a longitudinal axis A. The semiconductor layer furthermore includes at least two lateral segments forming electrical biasing arms that extend along a transverse axis Aorthogonal to the axis A

Optoelectronic device comprising a central segment tensilely strained along a first axis and electrically biased along a second axis

Optical and/or electronic device comprising a suspended, germanium-based membrane () and comprising an active zone () placed under tension by tensioning arms (), said device being characterized in that it comprises at least one tensioning arm () comprising nonparallel lateral sides (), the width of which increases with distance from the active zone ().

Device comprising a strained germanium membrane

The invention relates to a process for the formation of pores of controlled shape, dimensions and distribution in a polymer matrix comprising a step of embedding silicon nanowires and/or nanotrees in a nonpolymerized polymer matrix or a nonpolymerized polymer matrix in suspension or in solution in at least one solvent, a step of curing the polymer matrix, and a step of removing the silicon nanowires and/or nanotrees by chemical treatment. The process of the invention can be used for the manufacture of a proton exchange membrane fuel cell active layer. The invention has applications in the field of manufacture of proton exchange membrane fuel cells, in particular.
