Limb imaging of the Venus O2 visible nightglow with the Venus Monitoring Camera
A. GarcÃa Muñoz, R. Hueso, A. Sánchez-Lavega +4
We investigated the Venus O2 visible nightglow with imagery from the Venus Monitoring Camera on Venus Express. Drawing from data collected between April 2007 and January 2011, we s…
Transport properties of copper phthalocyanine based organic electronic devices
C. Schuster, M. Kraus, A. Opitz +2
Ambipolar charge carrier transport in Copper phthalocyanine (CuPc) is studied experimentally in field-effect transistors and metal-insulator-semiconductor diodes at various tempera…
Ambipolar blends of CuPc and C60: charge carrier mobility, electronic structure and its implications for solar cell applications
W. Bruetting, M. Bronner, M. Goetzenbrugger +1
Ambipolar transport has been realised in blends of the molecular hole conductor Cu-phthalocyanine (CuPc) and the electron conducting fullerene C60. Charge carrier mobilities and th…
Ambipolar charge carrier transport in mixed organic layers of phthalocyanine and fullerene
A. Opitz, M. Bronner, W. Bruetting
Mixed layers of copper-phthalocyanine (p-conductive) and fullerene (n-conductive) are used for the fabrication of organic field-effect transistors (OFETs) and inverters. Regarding…
A comparative investigation of thickness measurements of ultra-thin water films by scanning probe techniques
A. Opitz, M. Scherge, S. I. -U. Ahmed +1
The reliable operation of micro and nanomechanical devices necessitates a thorough knowledge of the water film thickness present on the surfaces of these devices with an accuracy i…
Nanofriction mechanisms derived from the dependence of friction on load and sliding velocity from air to UHV on hydrophilic silicon
A. Opitz, S. I. -U. Ahmed, M. Scherge +1
This paper examines friction as a function of the sliding velocity and applied normal load from air to UHV in a scanning force microscope (SFM) experiment in which a sharp silicon…
Virtual Planetary Space Weather Services offered by the Europlanet H2020 Research Infrastructure
N. André, M. Grande, N. Achilleos +25
The Europlanet 2020 Research Infrastructure will include new Planetary Space Weather Services (PSWS) that will extend the concepts of space weather and space situational awareness…
Differences of interface and bulk transport properties in polymer field-effect devices
S. Grecu, M. Roggenbuck, A. Opitz +1
The influence of substrate treatment with self-assembled monolayers and thermal annealing was analysed by electrical and structural measurements on field-effect transistors (FETs)…
