Stretchable, Printable Graphene-based Transistors |
| 초록 |
With the emergence of human interface technology, the development of new applications based on stretchable electronics such as conformal bio sensor and rollable display have been required. However, the difficulty in developing semiconducting materials with high stretchability required for such applications has restricted the range of applications of stretchable electronics. Here, we present stretchable, printable and transparent transistors composed of monolithically patterned graphene films. The graphene films that possess excellent mechanical, electrical and optical properties were used as a semiconducting channel as well as a source/drain electrode. The monolithic graphene transistor shows hole and electron mobilities of 1188 ± 136 and 422 ± 52 cm2/Vs, respectively and maintains stable operation at stretching up to 5% and even after 1000 times fatigue test. |
