Nowadays there is huge demand for more capacious, compact and faster memory storages. In this regard the resistive random-access memory (RRAM) with 3D cross point architecture filled out by organic based nano-composite film could become the new technological breakthrough. Such systems have two programmable high and low resistance states which can be controlled and probed by applying a voltage. Taking it into account, the morphology and electronic properties of nano-composite films based on blended aluminum, gold and silver nanoparticles into n-type organic semiconductor of fluorinated copper phthalocyanine (CuPcF4) have been investigated by means of TEM and SR-PES measurements as function of nominal amount of metal deposition. TEM measurements reveal organic film with self-assembled nanoparticles, whose size and distribution are strongly correlated with nominal amount of deposited metal. Moreover, comparative study of electronic properties self-assembled nanoparticles detects strong interaction of metal atoms with organic substrate.
