A TEMPERATURE-INDEPENDENT CONDUCTING STATE IN TETRACENE THIN FILM

Abstract
Anomalous electrical conductivity phenomena have been observed in thin tetracene films sandwiched between metal electrodes. The resistivity of the tetracene layer is observed to change from a high value (``off state'') to a low value (``on state'') upon the application of voltage. In the ``on state'' the resistivity is both temperature insensitive and photoinsensitive. A preliminary interpretation of this behavior is presented.
