Electron transport properties in fluorinated copper-phthalocyanine films: importance of vibrational reorganization energy and molecular microstructure.
Electron transport (ET) properties of a series of fluorinated copper-phthalocyanine (F(16)CuPc) thin films, which were deposited at different substrate temperatures (T(sub)) ranging from 30 to 150 degrees C, have been investigated by quantum mechanical calculations of the reorganization energy (lambda(reorg)), X-ray diffraction (XRD), atomic force microscopy (AFM), and microRaman spectroscopy. ...
متن کاملFluorinated copper phthalocyanine nanowires for enhancing interfacial electron transport in organic solar cells.
Zinc oxide is a promising candidate as an interfacial layer (IFL) in inverted organic photovoltaic (OPV) cells due to the n-type semiconducting properties as well as chemical and environmental stability. Such ZnO layers collect electrons at the transparent electrode, typically indium tin oxide (ITO). However, the significant resistivity of ZnO IFLs and an energetic mismatch between the ZnO and ...
متن کاملTransport properties of copper phthalocyanine based organic electronic devices
As a particular class of planar aromatic compounds, metal phthalocyanines are considered for numerous applications since they show a variety of interesting physical and chemical properties. In particular, the semiconducting copper phthalocyanine (CuPc), is employed in several optoelectronic devices such as organic light-emitting diodes or organic photovoltaic cells. The ambipolar charge carrier...
متن کاملStudy of excited states of fluorinated copper phthalocyanine by inner shell excitation
Near edge X-ray absorption fine structure (NEXAFS) spectra of hexadecafluoro copper phthalocyanine (FCuPc) films (thickness of 50 Å) on MoS2 substrates were observed near the carbon (C) and fluorine (F) K-edges. From the analysis of the dependence of C and F K-edge NEXAFS spectra on the photon incidence angle (α), the average molecular tilt angle was determined to be 30◦. The lowest and second ...
متن کاملNonequilibrium spin crossover in copper phthalocyanine
We demonstrate the nonequilibrium tip induced control of the spin state of copper phthalocyanine on an insulator coated substrate. We find that, under the condition of energetic proximity of many-body neutral excited states to the anionic ground state, the system can undergo a population inversion towards these excited states. The resulting state of the system is accompanied by a change in the ...
