  • Silicon nanospheres could be of interest for applications in electronics and optoelectronics. Here, Gumenniket al. demonstrate a nanosphere fabrication process based on an optical fibre drawing technique that is able to produce p and n-type spheres paired into rectifying bispherical junctions.

  • The thermal-draw technique offers fibre devices with a multiplicity of geometries, but these are constrainted to being translationally symmetric. Here, the authors disrupt this symmetry by applying selective capillary instability, resulting in electrically connected spherical photodetecting elements.

  • Capillary breakup in multimaterial fibers is explored for the self-assembly of optoelectronic systems. However, its insights primarily stem from numerical simulations, qualitative at best. The authors formulate an analytical model of such breakup, obtaining a window in the governing parameters where the generally chaotic breakup becomes predictable and thus engineerable.

  • Micro-electromechanical systems fabrication techniques are based on silicon micromachining processes, resulting in rigid and low aspect ratio structures. Here the authors demonstrate a flexible, high aspect ratio micro-electromechanical system in fibre enabled by an electrostrictive ferrorelaxor terpolymer layer.
