Colossal dielectric constant up to GHz at room temperature
S. Krohns, P. Lunkenheimer, Ch. Kant +5
The search for new materials with extremely high ("colossal") dielectric constants, required for future electronics, is one of the most active fields of modern materials science. H…
Dielectric quantification of conductivity limitations due to nanofiller size in conductive powders and nanocomposites
L. J. Huijbregts, H. B. Brom, J. C. M. Brokken-Zijp +2
Conducting submicron particles are well-suited as filler particles in non-conducting polymer matrices to obtain a conducting composite with a low percolation threshold. Going to na…
Doping, density of states and conductivity in polypyrrole and poly(p-phenylene vinylene)
I. N. Hulea, H. B. Brom, A. K. Mukherjee +1
The evolution of the density of states (DOS) and conductivity as function of well controlled doping levels in OC_1C_10-poly(p-phenylene vinylene) [OC_1C_10-PPV] doped by FeCl_3 and…
In situ determination of the energy dependence of the high-frequency mobility in polymers
I. N. Hulea, A. V. Pronin, H. B. Brom
The high-frequency mobility in disordered systems is governed by transport properties on mesoscopic length scales, which makes it a sensitive probe for the amount of local order. H…
Ageing effects around the glass and melting transitions in poly(dimethylsiloxane) visualized by resistance measurements
H. B. Brom, I. G. Romijn, J. G. Magis +2
The process of ageing in rubbers requires monitoring over long periods (days to years). To do so in non-conducting rubbers, small amounts of carbon-black particles were dispersed i…
A quantitative evaluation of metallic conduction in conjugated polymers
H. C. F. Martens, H. B. Brom
As the periodicity in crystalline materials creates the optimal condition for electronic delocalization, one might expect that in partially crystalline conjugated polymers delocali…
