Nonvolatile electric memory surface-type elements baseD on organic-on-organic CuPc-H<sub>2</sub>Pc heterojunction
Nonvolatile electric memory surface-type elements based on organic semiconductors CuPc and H2Pc were fabricated by vacuum deposition of the CuPc and H2Pc films on preliminary deposited metallic Ag and Cu films on glass substrate. In the I-V characteristics the memory effect was observed. The switching mechanism is attributed to electric-field-induced charge transfer from an organic electron donor to an acceptor. In the result the device switches from a low- to a high-conductivity state and back to low conductivity state if opposite polarity voltage was applied. This element con be used in electronics and in formation systenis.
