  • Publication number: 20240008294
    Abstract: The present invention relates to an organic thin film transistor (OTFT) comprising an organic semiconductor layer (2) arranged between a source terminal (3) and a drain terminal (4). The OTFT further includes a front gate (5) electrode arranged on one side of the organic semiconductor layer and a back gate electrode (6) arranged on the opposite side of the organic semiconductor layer. The front and back gate electrodes are arranged to control the current flow in the organic semiconductor layer upon application of a voltage and the back gate electrode is electrically connected to one of: the front gate electrode and the source terminal. OTFT's according to the present invention, with a connection between the back gate and the source or front gate, exhibit improved turn on voltage stability, lower power consumption and improved bias stress stability compared to single gate and back gate isolated OTFTs.

  • Publication number: 20210119157
    Abstract: The present invention provides an organic gate insulator (OGI) layer having a low dielectric constant (k), said organic gate insulator layer being over-coated with a cross-linked organic layer (OSPL) having a relatively high permittivity (k). The present invention also provides an electronic device comprising such an organic thin film transistor. The invention also provides a solution for producing said OSPL, and a process for producing said OSPL.
