Low voltage complementary organic inverters

Reliability study of organic complementary logic inverters using constant voltage stress

We performed constant voltage stresses with different bias conditions on all-organic complementary inverters. We found a 20% maximum variation of DC inverter parameters after a 10-s stress. However, the largest stress-induced degradation was found in the delay times, which increased by a factor as high as 7. This is mainly due to the threshold voltage variation of the p-type thin-film-transisto...

n-Channel organic thin film transistors and complementary inverters

n-channel organic thin film transistors (OTFTs) with field-effect mobility comparable to that typically reported for pchannel pentacene TFTs were fabricated on oxidized silicon wafers using N,N'-ditridecylperylene-3,4,9,10tetracarboxylic diimide (PTCDI-C13H27) as the semiconductor. Au, Cr, Al, and LiF/Al source and drain contacts were studied. Accumulation mode n-channel transistor operation wa...

Low Power Complementary Organic Comparators

In this work, we present a novel organic complementary comparator constructed of Pentacene P-channel and Fullerene N-channel thin-film transistors. These organic semiconductor materials are chosen due to their popularity and high effect-field mobility. We fabricated two new organic fieldeffect transistor types, then we measured key parameters in order to create models being used in integrated c...

Gravure printed low voltage polymer transistors and inverters

Organic nanodielectrics for low voltage carbon nanotube thin film transistors and complementary logic gates.

We report the implementation of three dimensionally cross-linked, organic nanodielectric multilayers as ultrathin gate dielectrics for a type of thin film transistor device that uses networks of single-walled carbon nanotubes as effective semiconductor thin films. Unipolar n- and p-channel devices are demonstrated by use of polymer coatings to control the behavior of the networks. Monolithicall...
