| Outline of Final Research Achievements |
Applications of electronics on, or even in the human body require devices to be safe and consume low energy, which requires an aggressive scaling of the operating voltage ideally down to sub-1V levels. Here we demonstrate organic transistor with a high-k titanium oxide gate dielectric with a mobility of 1.45 cm2/Vs when operated at 1V. We show organic pseudo-CMOS inverter able to invert an input 0.3V driving-voltage and the inverter with 0.5V driving-voltage able to operate at a 10Hz square wave input. The total delay time of the inverter under such conditions is 24 ms. The here-developed methods allow low voltage operational organic transistor circuits to be fabricated in a highly reliable manner on virtually any substrate, applicable for flexible, wearable and implantable electronics in health care, medical diagnostics and patient monitoring as well as consumer appliances.
