CHAPTER 16

Ambipolar Materials for Gas Sensing

Ambipolar sensors have only appeared in the past decade, i.e. very late compared to the first ambipolar electronic devices. They have been obtained with resistors, organic field-effect transistors and heterojunctions. It is not sufficient just to have ambipolar materials in order to observe ambipolar sensors. A key point is the ability to stabilize the p and n states by changing one external parameter. For further developments, it will be necessary to master a trigger that is capable of going from p-type to n-type behavior and vice versa. This can be an external bias, as in transistors, or any form of light.
