Original Kurzfassung:
A comprehensive study concerning the reproducibility and stability of organic n-type field effect transis-
tors is presented. C60 based OFETs were chosen to investigate the fabrication reproducibility and the long
term stability because C60 is a high mobility n-type material. We fabricated 48 transistors and each tran-
sistor was measured for 24 h inside the glove box. To test for life time stability ? long term measurements
up to three months have been undertaken. We report about the fluctuations in the device parameters
of all investigated transistors by comparing the transfer characteristics, and on/off ratio for short time
and long time measurements. C60 based OFETs showed good reproducibility and stability for short time
measurements and a decay for long time measurements.
