제목 Wafer-Scale Patterning of Reduced Graphene Oxide Electrodes by Transfer-and-Reverse Stamping for High Performance OFETs
초록 We report a wafer-scale patterning method of solution-processed graphene electrodes, named as the transfer-and-reverse stamping method. The patterning method begins with transferring a highly uniform reduced graphene oxide thin film, which was pre-prepared on a glass substrate, onto hydrophobic silanized (rigid/flexible) substrates. Patterns of the as-prepared reduced graphene oxide films are then formed by modulating the surface energy of the films and selectively delaminating the films using an oxygen-plasma-treated elastomeric stamp with patterns. Reduced graphene oxide patterns with various sizes and shapes could be readily formed onto an entire wafer. Also, they could serve as the source/drain electrodes for benchmark n- and p-type organic field-effect transistors with enhanced performance. Furthermore, our simple, inexpensive, and scalable electrode-patterning-technique leads to assembling organic complementary circuits onto a flexible substrate successfully
