  • Abstract
    The characteristics of the wide-narrow GNR T-FET were studied. The proposed device utilizes the small bandgap of wide-GNR to achieve high ION and the high bandgap of narrow-GNR to attain low IOFF. The design space for the bandgap/width of the two regions was studied. The design parameters can be optimized to achieve ION as high as 1.3 mA/μm, ION/IOFF ratio as high as 109, and S as small as 10 mV/dec at VDD=0.5 V. Compared to the HP MOSFET with Lg=25 nm, the wide-narrow GNR T-FET exhibits 2X and 104X improvement in ION and ION/IOFF ratio at VDD=0.5 V, which makes it suitable for HP/LP applications.
