    Porous InP as piezoelectric component in magneto-electric composite sensors [Articol]
    (io, 2011) Gerngross, M.-D.; Sprincean, Veaceslav; Leisner, M.; Carstensen, J.; Föll, H.; Tiginyanu, Ion
    We report on the fabrication of cheap piezoelectric porous InP templates by electrochemical etching and additional purely chemical post-etching and on the galvanic filling of the resulting nanopore array with Ni-Fe using a highly viscous electrolyte. The d14 component of porous InP is found to be around a stunning |60| pm/V. The deposited Ni-Fe shows a very narrow hysteresis loop with low coercive field strength (170 G) and very low remanence (0.005 emu).
