|Towards future electronics, we study ultimately-scaled
devices and novel functional devices such as flexible devices, utilizing
specific properties of nanostructure and nanomaterials such as carbon nanotubes.
We also study ecotechnologies to manufacture electron devices with printing technology for realizing a "low-carbon society".
New World's first all-carbon ICs towards formable electronics; published in Nature Communications
We have created the world's first all-carbon integrated circuits consisting of transistors and wirings using only carbon nanotubes, with expected applications to transparent high-performance flexible devices. Furthermore, such all-carbon ICs can be thermoformed into arbitrary 3D shape. The results make it possible to achieve a fusion of electronic devices with plastic products, which can lead to the creation of plastic electronic devices that feature both designability and functionality. This result was published in Nature Communications. Here is press release
World's first carbon naotube ICs on transparent plastic film; published in Nature Nanotechnology
We have developed a simple and fast process to manufacture high quality carbon nanotube-based thin film transistors (TFT) on a plastic substrate. The world’s first sequential logic circuits using carbon nanotubes has been realized. The results were published in nature nanotechnology (Impact Factor = 30.3).
MSI by carbon nanotubes
We have realized an ring oscillator where 108 carbon nanotube thin-film transistors (TFTs) were integrated. This IC is the first Medium-scale integration (MSI) with carbon nanotube devices. This study has been published in APEX. Appl. Phys. Exp. 3, 115101 (2010)
New One-step micro-patterning of CNT films; publised in ACS Nano
We develepped a technology to form micro-patterns of carbon nanotube (CNT) film with a resolution of <10 μｍ by onestep transfer process. Based on this technique, easy fabrications of high-performance CNT transparent conductive films with microgrid structure and capacitive touch sensors have been demonstrated. This technique opens a way to low-cost, energy- and material-saving production of transparent conductor devices. This work was published in ACS Nano (IF=12.1).
