Abstract
In the present work, we report on development of three-dimensional flexible architectures consisting
of an extremely porous three-dimensional Aerographite (AG) backbone decorated by InP micro/
nanocrystallites grown by a single step hydride vapor phase epitaxy process. The systematic
investigation of the hybrid materials by scanning electron microscopy demonstrates a rather
uniform spatial distribution of InP crystallites without agglomeration on the surface of Aerographite
microtubular structures. X-ray diffraction, transmission electron microscopy and Raman scattering
analysis demonstrate that InP crystallites grown on bare Aerographite are of zincblende structure,
while a preliminary functionalization of the Aerographite backbone with Au nanodots promotes
the formation of crystalline In

nanowires as well as gold-indium oxide core-shell nanostructures.
The electromechanical properties of the hybrid AG-InP composite material are shown to be better
than those of previously reported bare AG and AG-GaN networks. Robustness, elastic behavior and
excellent translation of the mechanical deformation to variations in electrical conductivity highlight the
prospects of AG-InP applications in tactile/strain sensors and other device structures related to flexible
electronics
