Highly polar groups and supramolecular order enable charge injection and long-range conductivity in organic materials without extended Ï-systems
H. Mager, A. A. Butkevich, S. Klubertz +12
Electronic conductivity in organic materials is well-established. Both semiconductive and metallic behavior is observed in (quasi) 0-, 1-, 2- and 3-dimensional carbon-based materia…

Barkhausen noise in the columnar hexagonal organic ferroelectric BTA
Andrey Alekseevich Butkevich, Fabian T. Thome, Toni Seiler +2
Upon a polarization reversal within a ferroelectric material, one stable state changes into another which is typically described by a progression of switching events of smaller fra…

Barkhausen noise in the organic ferroelectric copolymer P(VDF:TrFE)
Andrey Alekseevich Butkevich, Marcel Hecker, Toni Seiler +1
Polarization reversal within a ferroelectric material is commonly described as a progression of smaller switching events, giving rise to crackling or Barkhausen noise. While studie…
