Organic diode with high rectification ratio made of electrohydrodynamic printed organic layers
Source abstract
Abstract
In this paper, an all-printed organic diode to reveal a high rectification ratio (∼1.2 × 104) is proposed using organic heterojunction materials N,N′-Bis(3-methylphenyl)-N,N′-diphenylbenzidine (TPD) and fullerene (C60). The proposed organic diode is fabricated as a structure of ITO/TPD/C60/Al on a glass substrate through an all-printed electrohydrodynamic (EHD) technique, which has an effective area of 2 × 2 mm2. The threshold voltage of the forward bias is 1.2 V and the current density reaches 550 mA/cm2 at 3 V. The device is characterized by current voltage I-V at temperature 30°C to 120°C, and junction capacitance is analyzed at 4 kHz frequency at ±2 V. To verify the successful construction of all layers deposited through the EHD technique, morphology analysis was carried out with FE-SEM. From these measured electrical characteristics, suitability for rectification purposes in printed electronics is confirmed.
