This is how a CMOS(complementary metal oxide semiconductor) would look like…….

Scientists at the Max Planck Institute for Solid State Research in Stuttgart and at the Universities of Stuttgart and Erlangen have constructed complementary circuits from organic transistors characterised by low supply voltages and low consumption values.

These energy-saving electronic components consist of two different transistor types. The new organic electronic components can be operated with significantly lower voltages than previous organic circuits – voltages, such as those supplied by normal household batteries from 1.5 to 3 volts…

These are two photos of flexiblecircuits created using carbon nanotubes.

Transistors made from organic materials have an advantage over normal silicon transistors. They can be constructed on flexible surfaces, such as plastic film, making organic circuits ideal for portable and mobile devices. However, until now, organic transistors have also had a big disadvantage: they consumed too much energy. Scientists have now constructed energy-saving organic circuits.

Organic semiconductor created using organic substances….

Up to now, organic circuits have mostly been realised in the form of unipolar circuits, which consist of transistors of just one type only (either p channel or n channel). In this kind of unipolar circuit, there is a constant undesirable cross-current, whereas with the complementary construction, one of the two transistors blocks the flow of the current – an opportunity to save energy

” Organic complementary circuits can consequently be used everywhere where products need to be simultaneously robust and mobile, for example in a portable, battery-powered flat screen.
