About some properties of terthiophene thin films otained in the presence of a red hot wolfram filament

Terthiophene powder was synthesised following the cross-coupling Grignard reaction. A tungsten crucible with a multiholed cover was used to evaporate the powder under vacuum. A red-hot wol fram filament is placed between the evaporation source and the substrates. The variations of the properties of...

Description
Summary:Terthiophene powder was synthesised following the cross-coupling Grignard reaction. A tungsten crucible with a multiholed cover was used to evaporate the powder under vacuum. A red-hot wol fram filament is placed between the evaporation source and the substrates. The variations of the properties of the deposited films were studied using the evaporation rate and the filament temperature as parameters. It is shown that there is some activation of the terthiophene by the hot wolfram filament.
