A polymer with built-in charge for increasing the organic diode efficiency

Abstract

In the present paper the problem which is important for modern microelectronics - a raise of effectiveness of carrier charge transfer by means of making an internal field is considered. For this purpose we create structures, which besides standard layers, such as HTL and ETL, contain layers consisting of polymers with the internal charge, such as PSS, PAH. Theoretical calculations show that the addition of these layers into multilayer OLED structures can lower potential energy barrier between organic layers and electrodes, and this will allow rising the effectiveness of the charge transfer emission and consequently also a number of excitons in working area of the display.
