Abstract : We have investigated the organic film growth of perylene tetracarboxylic diimide (PTCDI) and of palladium phthalocyanine (Pd(Pc)) on Pt(001), Pt(111) and Au(001). We are interested in the realisation of metal/PTCDI/Pd(PC)/metal heterostructures with nanometric thickness, obtained by MBE under UHV.
Using AES and STM, we show that PTCDI and Pd(Pc) deposited on Pt(111) and Pt(001) grow according to the Stransky-Krastanov mode.
The electronic properties of increasing thickness films on Pt(001) have been deduced by REELS, showing a slow electronic gap opening.
On Au(001), we show that the first layer of Pd(Pc) is ordered according to the adsorbed quantity, in a square or rectangular unit mesh. PTCDI forms a rectangular unit mesh with parameters close to those obtained by XRD on PTCDI monocrystal.
Using a square Pd(Pc) layer adsorbed on Au(001) as substrate, we show that the deposition of PTCDI is in epitaxy. I(V) curves obtained by STS on this heterostructure are similar to a diode characteristic.
