raman spectra of al-alo/sub x/-mpc-m' tunnel diodes, where m=cu or h/sub 2/, m'=ag or pb, and pc=phthalocyanine, are reported no evidence is found for chemical modification of either cupc or h/sub 2/pc in any step of the device fabrication process. by observing the raman spectra of functioning tunnel diodes, it is demonstrated that no electrochemical modification of cupc occurs under bias conditions of +or-1.3 v. while ultrathin mpc layer devices prior to m' deposition show strong raman scattering only for p-polarized radiation, the completed devices (m'=pb or ag) scatter both s- and p-polarized radiation
