New varistor-type polymer composites for low-voltage application have been developed. The filler is made of commercially available doped ZnO-varistor powder. The polycrystalline filler particles act as varistors due to their typical grain-boundary st

For the current transport mechanism between the n+ Si emitter and the screen printed silver contact, there is strong experimental evidence that the largest current contribution flows through Ag crystallites directly connected with the silver finger,

We used the Scanning Nearfield Acoustic Microscope-a nontouching profilometer with a conducting tip-both to pole thin ferroelectric VDF-TrFE copolymer films and to subsequently monitor the resulting pie-zoelectrically stimulated surface motion. For t

The ferroelectric switching time in thin vinylidenefluoride - trifluoroethylene copolymer films - determined by the technique of continous polarization reversal - shows a strong dependence on the temperature, the switching rate and on the electrical

Very thin VDF-TrFE copolymer films were prepared by spin coating ranging in thickness down to 100 nm. Their dielectric and ferroelectric behaviour was measured as a function of thickness. Furthermore their surface roughness and their local piezoelect

Very thin VDF-TrFE copolymer films were characterized on the basis of low-field dielectric experiments, high-field ferroelectric hysteresis measurements, and fast ferroelectric switching experiments. The electrical DC-conductivity of thin copolymer f

Polymer based composites are very attractive materials for a plurality of technical applications. For electrical purposes the resistivity of such materials can be tuned over many orders of magnitude from highly insulating (1014&cm) to well conducting

We used the scanning nearfield acoustic microscope−a nontouching profilometer−to investigate the local piezoelectric activity of thin vinylidene fluoride trifluoroethylene copolymer films with a lateral resolution of 1 μm. For metallized as well

An industrially important class of passively smart materials is electrically nonlinear polymer composites. The transition of conducting composites from low to high resistivity can be utilized for current limitation. Due to Joule losses the material i
