| 總結: | The authors demonstrate a new organic memory system, using pentacene as the active
semiconductor layer and citrate-stabilized gold (Au) nanoparticles as charge storage elements. A
pronounced clockwise capacitance-voltage (C-V) hysteresis is observed with a memory window of
1.25–2.05 V achievable under 5–10 V programing range. Similar clockwise C-V hysteresis
window and an almost constant full width at half maximum of the conductance peaks in
conductance-voltage (G-V) characteristics, obtained in the frequency range of 50 kHz–1 MHz,
indicated that positive charge trapping/detrapping originated mainly from the Au nanoparticles. |
