A 3µm channel, ink-jet printed CNT-TFT for phased array antenna applications

A top-gate CNT-TFT with a channel length of 3μm was fabricated via ink-jet printing on a flexible substrate. The source and drain were designed to contain triangular ends in order to facilitate fabrication of channel lengths less than 5μm. Output characteristic (Ids-Vds) was measured to observe the electrical behavior, and an on/off ratio over 1000 at Vds = 2V was achieved.
