Tin oxide nanowire sensors for highly sensitive detection of toxic gases

Koeck A., Brunet E., Griessler C., Maier T., Mutinati G., Steinhauer S., AIT Austrian Institute of Technology GmbH, AT

Numerous applications ranging from industrial process control to personal safety systems and environmental monitoring have a strongly increasing demand for highly sensitive gas detecting devices. We present nanosensors based on SnO2-nanowires, which are extremely sensitive [...]

Sensor for real-time monitoring of food degradation

Ibrisimovic N., Bauer M., Pittner F., University Vienna, AT

The aim of our novel approach was to create a simple and cheap sensor providing reasonable sensitivity and selectivity to indicate the “best use before” period combined with a memory effect that cannot easily be [...]

Structure Generation for the Numerical Simulation of Nano-Scaled MOSFETs

Kernstock C., Karner M., Baumgartner O., Gehring A., Holzer S., Kosina H., Global TCAD Solutions, AT

An accurate and predictive numerical simulation of MOS transistor in the deca-nanometer channel length regime relies on the precise mapping of the physical device into a simulation model. A quick and accurate method which allows [...]

FIB generated antimony nanowires as chemical sensors

Lugstein A., Schöndorfer C., Bertagnolli E., Technical University Vienna, AT

Sb nanowires with a homogeneous distribution of diameters of about 25 nm and length up to several microns are synthesized in a self-assembling process without any additional material source at room temperature by the impact [...]

Sensor for real-time monitoring of food degradation

Ibrisimovic N., Bauer M., Pittner F., University Vienna, AT

The aim of our novel approach was to create a simple and cheap sensor providing reasonable sensitivity and selectivity to indicate the “best use before” period combined with a memory effect that cannot easily be [...]

Adaptive Energy Integration of Non-Equilibrium Green’s Function

Baumgartner O., Karner M., Holzer S., Pourfath M., Grasser T., Kosina H., TU Wien, AT

Within the non-equilibrium Green's function formalism numerical integration plays an important role. Several adaptive integration methods were realized and compared regarding convergency within a self-consistent Schrödinger-Poisson loop, computation time and memory consumption.

Investigation of Vector Discretization Schemes for Box Volume Methods

Triebl O., Grasser T., Christian Doppler Laboratory for TCAD in Microelectronics, AT

The usage of the box integration method in Technology CAD environments is investigated. Focus is taken on methods how to discretize vectors in box volumes. The authors of this paper discuss three different methods for [...]

Single Molecule Interaction Forces and Recognition Imaging

Kienberger F., Chtcheglova L.A., Ebner A., Puntheeraunrak T., Gruber H.J., Hinterdorfer P., University of Linz, AT

In recent years, considerable attention has focused on biological applications of the atomic force microscope (AFM), in particular on high-resolution imaging of individual biological molecules and on the measurement of molecular forces under near-physiological conditions. [...]

nanometric thinfilm sensor

Bauer M., Putz E.M., Pittner F., University of Vienna, AT

We want to present an optical thin film sensor chip able to detect the decay of food through a specific color change. The design of the chip relates to a phenomenon, the so called “anomalous [...]

Atmospheric Pressure Ion Deposition – Selected applications

Nußbaumer L., Saf R., Piber M., Institute for Chemistry and Technology of Organic Materials, AT

Atmospheric Pressure Ion Deposition: a novel experimental setup allows the processing of various materials (e.g. polymers, small molecules, nanoparticles and biomolecules) into thin structured films.This method generates by means of electrostatic forces a fine dispersed [...]
