In this work, we study the electrical characteristics of planar poly-Si junctionless (JL) thin-film transistors (TFTs) with 10 nm-thick channel and various gate width. The output current of JL devices is drastically larger than that of the control device with an undoped channel, owing to the abundant carriers contained in the channel of the JL devices which tends to reduce both channel and source/drain series resistances. Subthreshold swing of the JL devices is found to be larger than the control ones, owing to the existence of a depletion layer in the channel. Nonetheless, excellent on/off current ratio (>10(7)) is achieved, thanks to the use of the ultra-thin channel.
