ABSTRACTA new oxydative-resistant, fusible and processible ethylene/acetylene copolymer has been synthesized. The content of rigid (acetylene) and flexible (ethylene) fragments has been widely varied. The structure of the nascent powders and the films compressed at room temperature have been investigated by SEM and WAXS. DSC has been used for studying the thermal properties. DC conductivity of the iodine doped samples has been measured as a function of temperature. It is shown that the doping leads to arising conductivity in the samples even at 10 Mol % acetylene fragments in copolymer. The conductivity up to 10−3 S/cm is reached for the samples with acetylene fragment concentration about 20 Mol %. It is found that a charge carrier transport in investigated copolymers is caused by doped polyacetylene fragments and described by the hopping Mechanism.

The influence of the used substrate and the boron doping concentration of the charge-transport properties of solid-phase crystallized polycrystalline silicon (poly-Si) is explored. The samples were characterized using temperature dependent transport measurements to determine mobility, carrier concentration, and conductivity. While Arrhenius plots of the hole concentration cannot be used to determine the position of the Fermi energy, a detailed analysis of the temperature dependent carrier concentration shows a Meyer–Neldel and an anti-Meyer–Neldel rule. Charge transport in poly-Si on SiN coated Borofloat glass with a boron concentraion [B] < 1016 cm–3 is limited by phonon scattering. On the other hand, for all poly-Si samples on Corning glass and poly-Si on SiN coated Borofloat glass with [B] > 1016 cm–3 charge-carrier transport is governed by thermionic emission over potential barriers. The data are discussed in terms of the Baccarani transport model.
