MRS Communications, the recently launched journal from the Materials Research Society and Cambridge University Press, was designed to serve the fast-moving international materials research community. Focused on reporting cutting-edge materials research and offering quick turnaround at both the editorial and production stages of publication, the journal published its first article less than two months after its official launch at the 2011 MRS Spring Meeting in San Francisco. The inaugural Rapid Communications article details an important breakthrough by a team of Japanese and German researchers.
The researchers—Tomoyuki Yokota, Tsuyoshi Sekitani, Yu Kato, Kazunori Kuribara, and Takao Someya (The University of Tokyo); Ute Zschieschang and Hagen Klauk (Max Planck Institute for Solid-State Research); Tatsuya Yamamoto and Kazuo Takimiya (Hiroshima University); and Hirokazu Kuwabara and Masaaki Ikeda (Nippon Kayaku Co., Ltd.)—report that they have achieved a transconductance of 0.76 S/m for organic thin-film transistors with 4 V-operation. The team writes, “This is the highest transconductance reported for organic TFTs fabricated using printing, to the best of our knowledge.” The first Rapid Communications paper (DOI: 10.1557/mrc.2011.4) is freely available on Cambridge Journals Online (CJO).
The transconductance report is the first in the new journal’s Rapid Communications section (defined as a concise presentation of a study with broad interest showing novel results).
The first published paper shows that, thanks to ultra-low volume (subfemtoliter) inkjet nozzles, small transistors (channel length ~1 μm) were fabricated using electrodes printed from nanoparticle metal inks. The small dimensions allowed the researchers to demonstrate low-power and high-speed operation (theoretically up to a few MHz) of organic transistors, a requirement for useful circuits.
The researchers show that organic and printed electronics are not limited to large and slow devices, but can be extended to fast and miniaturized circuits while remaining compatible with low-cost fabrication on cheap flexible substrates. In general, these capabilities widen the spectrum of potential applications of this technology.
MRS Communications, a full-color, online-only publication, offers authors an exceptionally rapid review process and time-to-publication, while also providing a swift and direct channel to the global 16,000-strong MRS membership and to the international network of leading academic, industrial and government libraries worldwide served by Cambridge University Press. The first full issue of the journal will appear later this year.
