Use of self-assembled layers for checking the threshold voltage of organic transistors

摘要

The invention relates to an electronic device comprising at least two organic transistors having different threshold voltages. The device comprises at least two transistors, each including a self-assembled layer of molecules having dipole moments that differ from one another by an absolute value of between 0.2 and 10 debye. The invention is particularly suitable for use in the field of electronic circuit production.
