The trap DOS in small molecule organic semiconductors: A quantitative comparison of thin-film transistors with single crystals
Wolfgang L. Kalb, Simon Haas, Cornelius Krellner +2
We show that it is possible to reach one of the ultimate goals of organic electronics: producing organic field-effect transistors with trap densities as low as in the bulk of singl…
Calculating the trap density of states in organic field-effect transistors from experiment: A comparison of different methods
Wolfgang L. Kalb, Bertram Batlogg
The spectral density of localized states in the band gap of pentacene (trap DOS) was determined with a pentacene-based thin-film transistor from measurements of the temperature dep…
Low-voltage organic transistors and inverters with ultra-thin fluoropolymer gate dielectric
M. P. Walser, W. L. Kalb, T. Mathis +1
We report on the simple fabrication of hysteresis-free and electrically stable organic field-effect transistors (OFETs) and inverters operating at voltages <1-2 V, enabled by the a…
Oxygen-related traps in pentacene thin films: Energetic position and implications for transistor performance
Wolfgang L. Kalb, Kurt Mattenberger, Bertram Batlogg
We studied the influence of oxygen on the electronic trap states in a pentacene thin film. This was done by carrying out gated four-terminal measurements on thin-film transistors a…
Defect healing at room temperature in pentacene thin films and improved transistor performance
Wolfgang L. Kalb, Fabian Meier, Kurt Mattenberger +1
We report on a healing of defects at room temperature in the organic semiconductor pentacene. This peculiar effect is a direct consequence of the weak intermolecular interaction wh…
Organic small molecule field-effect transistors with Cytop(TM) gate dielectric: eliminating gate bias stress effects
Wolfgang L. Kalb, Thomas Mathis, Simon Haas +2
We report on organic field-effect transistors with unprecedented resistance against gate bias stress. The single crystal and thin-film transistors employ the organic gate dielectri…
