  We report a study of the electron transport (ET) properties at the nanoscale
(conductive-AFM noted C-AFM thereafter) of individual Prussian Blue Analog
(PBA) cubic nanocrystals (NCs) of CsCo(III)Fe(II), with size between 15 and 50
nm deposited on HOPG. We demonstrate that these PBA NCs feature an almost size
independent electron injection barriers of 0.41 +/- 0.02 eV and 0.27 +/- 0.03
eV at the CsCo(III)Fe(II)/HOPG and CsCo(III)Fe(II)/C-AFM tip, respectively, and
an intrinsic electron conductivity evolving from largely dispersed between ca.
5E-4 and 2E-2 S/cm without a clear correlation with the nanocrystal size. The
conductivity values measured on individual nanocrystals are higher by up to 5
decades than those reported on PBA films.
