This paper presents a printed organic complementary technology on flexible plastic substrate with high performance N and P-type Organic Thin Film Transistors (OTFTs), based on small-molecule organic semiconductors in solution. Challenges related to the integration of both OTFT types in a common complementary flow are addressed, showing the importance of(More)
We report on the effect of the deposition of self-assembled monolayers (SAMs) on the source and drain electrodes on the contact resistance and mobility in organic thin film transistors (OTFTs). Ultraviolet photoelectron spectroscopy (UPS) shows a variation of the work function of the electrodes depending on the SAM. OTFTs were fabricated with solution(More)
Flexibility will significantly expand the application scope of electronics, particularly large-area electronics. Over the last ten years, printed organic electronic is believed to be one of the next major technological breakthroughs in the field of microelectronic and the use of printing technology to process organic fieldeffect transistors (OFETs) opens(More)
This article deals with the development of force actuator buttons for haptic feedback applications. Finite Element Method (FEM) models were used to design high performances piezoelectric actuators able to promote force restitution that can be sensed by a finger. We present first a comparison between analytical modeling and displacement measurement of(More)
The aggressive scaling of the gate oxide leads to direct gate tunneling current, which affects the floatingbody effects in partially-depleted SOI MOSFETs. Experiments and simulations show that the gate-to-body current charges the body causing an unexpected ‘kink’ effect to occur at low drain voltage. This kink results in a second peak of transconductance,(More)
