Novaled's PIN Doping technology is not limited to OLED applications but is relevant for
organic TFTs where the carrier injection from drain and source into the organic
material has a major influence on the device performance.
Novaled‘s dopants are perfectly working with a wide range of OTFT materials
and can be processed both in vacuum and in solution.
Controlled p- and n-doping by using Novaled PIN OLED® technology allowes for:
Reduced contact resistance at Source/Drain
Use of less expensive contact material (replace Gold)
Definition of conduction type for a wide range of materials
Increased mobility
Control of threshold voltage
High response frequency.
The success of classical silicon CMOS technology is based on the combination of p-type and n-type silicon transistors. Similar organic complementary circuits are desired by organic industry. With Novaled p- and n-type dopants this vision can be realized: Both p- and n-type field-effect transistors can be accomplished side by side based on a single semiconductor layer by controlled p- and n-doping of the contact regions.
