| Abstract(in English) | N-shaped negative differential resistance(NDR)with high peak-to-valley current ratio(PVR)and low onset voltage(V_NDR)are clearly observed in 50-nm gate ridge-type InGaAs/InAlAs quantum wire field-effect transistor (QWR-FET).The characteristic of NDR is improved more than that of previously reported NDR devices.The low onset voltage of NDR(V_NDR)and its dependence on the gate voltage are attributed to the real space transfer of channel carriers into a barrier layer underneath the gate by field-assisted tunneling.The NDR characteristic of the QWR-FET is enhanced compared with that of InGaAs/InAlAs quantum well field-effect transistor(QW-FET).The narrower channel-width and shorter gate-length effectively improve in the PVR and V_NDR. |
