A NEW TECHNIQUE FOR OBTAINING TIME-OF-FLIGHT SIGNALS IN A ONE-DIMENSIONAL POLYMER SINGLE-CRYSTAL

This paper presents a new technique for observing carrier motion in the polymer bis(p-toluene sulphonate) ester of 2,4-hexadiyne-1,6-diol (PDATS). Using a three-electrode system, time-of-flight signals can be observed under low carrier density, bipolar conditions. A direct determination of carrier drift velocity can thus be obtained. Qualitative explanations for the action of this technique are given and comparisons are made of the results found using this technique with those found using surface configuration Kepler/LeBlanc time-of-flight experiments.
