OBJTs (Organic Bipolar Transistors) Based on Crystalline Rubrene Thin Films


New technical paper titled “Organic bipolar transistors” from researchers at Technische Universität Dresden, NanoP, Technische Hochschule Mittelhessen, University of Applied Science, and ALBA Synchrotron.

Abstract (Partial)
“Here we present organic bipolar transistors with outstanding device performance: a previously undescribed vertical architecture and highly crystalline organic rubrene thin films yield devices with high differential amplification (more than 100) and superior high-frequency performance over conventional devices. These bipolar transistors also give insight into the minority carrier diffusion length—a key parameter in organic semiconductors. Our results open the door to new device concepts of high-performance organic electronics with ever faster switching speeds.”
