- Abstract
- This brief proposes the use of a bridge transistor as a means of achieving early saturation characteristics of drain current. To investigate the electrical properties of the bridge transistor, we introduce materials capable of forming homojunction 2,7-Dioctyl1benzothieno3,2-b1 benzothiophene (C8-BTBT), heterojunction dinaphtho2,3-b:2',3'-fthieno3,2 -bthiophene (DNTT), and Schottky junction (Au) as bridge layers, along with the C8-BTBT-based channel. Our findings reveal early saturation characteristics of drain current in bridge transistors with Schottky junction. Through contact resistance extraction and 2-D numerical simulation, we suggest that the early current saturation behavior is due to the additional contact resistance and depletion region.
