通过引入划船栅极结构,在有机薄膜晶体管中观察到非易失性记忆效应。划船栅由一层纳米厚度的Al薄膜组成,该薄膜被热沉积在SiO2绝缘体上,并暴露在空气中自然氧化。可以看出,在黑暗和光照条件下,晶体管的电流-电压特性表现出明显的滞后行为和存储圈,表明晶体管可以作为非易失性存储元件。讨论了铝浮栅在黑暗和光照条件下的电荷俘获作用机理。
A nonvolatile memory effect was observed in an organic thin-film transistor by introducing a Boating gate structure. The Boating gate was composed of an Al film in a thickness of nanometers, which was thermally deposited on a SiO2 insulator and exposed to air to spontaneously oxidize. It can be seen that the transistors exhibit significant hysteresis behaviors and storage circles in current-voltage characteristics in the dark and under illumination, indicating that the transistors may act as a nonvolatile memory element. The operational mechanism is discussed in the cases of dark and illumination via charge trapping by the Al floating gate.
