In this work, a novel method combining fabrication of nonlithographic Au-film over nanosphere (AuFON) with gradual rapid thermal annealing (RTA) treatment was developed to produce a high performance of surface-enhanced Raman scattering (SERS) substrate. The highly uniform and periodic AuFON was achieved by the downscaling processs in the modified nanosphere lithography technique using 100-nm polystyrene...
Nanopatterning of Au-nanoarray on an indium tin oxide (ITO) electrode using efficient and low-cost nanospheres lithography (NSL) is reported. Convective self-assembly of 500 nm polystyrene (PS) nanobeads was found to effectively provide a well-ordered monolayer template for Au deposition with the coverage of about 90% on ITO. A simple Au-nanoparticles (AuNPs) spin coating was performed. It is observed...
This work presents a flexible carbon based memory with the Al/graphene oxide (GO)/ITO structure fabricated at room temperature. The Al/GO/ITO devices show the unipolar resistive switching behavior with the resistance ratio to over 30, and sustain over 250 cycling without any resistance window closure. However, the retention fails due to the resistance increase of low resistance state (LRS). The mechanisms...
