Abstract
- Abstract: A development of the conventional transfer-length method (TLM) for organic transistors’ contact resistance evaluation is proposed. By adding the dissipated power in access resistance and in the channel, we found that TLM can be extended to the non-linear region, i.e., up to saturation regime, which is widely believed to be a barrier for TLM application now. To improve the extraction accuracy and stability, a modified TLM version is used for the operation at small gate voltages. This modified power TLM is applied to polymer and pentacene field-effect transistors and proved as a useful tool for the contact resistance evaluation as a function of gate and drain voltages from common current–voltage characterizations.
