| Outline of Final Research Achievements |
We have developed a self-alignment process for nano-carbon field effect transistors (FETs) using a carbon nanowall (CNW). Higher growth temperature enlarges the grain size in CNWs, and this results in a decrease in carrier scattering at the grain boundary. Using the low temperature buffer, we can improve the electric properties of channels. We also discussed about the plasma processes to improve the device properties of CNW-FETs. And we measured the pH dependence of the device properties. The binding molecules are known to be the key components for bio-sensors. We estimated the size of detection molecules of glycan for influenza viruses using atomic force microscopy. The typical molecule size is around 1 nm, and this may be suitable for electronic detection using a FET structure. We have also checked the selectivity of the graphene bio sensor. Furthermore, we have also evaluated the specific binding properties for the wild type of influenza virus in Egypt, Indonesia, and so forth.
