Electrical and structural characterization of CuPc/P(VDF/TrFE)/C60

研究了CuPc/P(VDF/TrFE)/ c60的电特性。CuPc/P(VDF/TrFE)/ c60的开关电流为双峰，而CuPc/P（VDF/TrFE）和P(VDF/TrFE)/ c60的开关电流为双峰。C-V特性还揭示了P（VDF/TrFE）的偶极子会在CuPc/P(VDF/TrFE)/C_60的两个界面上同时调制P型和n型有机半导体的电态（耗竭或积累）。

The electrical characteristics of CuPc/P(VDF/TrFE)/C60were investigated. The switching current of CuPc/P(VDF/TrFE)/C60exhibited the triple peaks on positive bias, although these of CuPc/P(VDF/TrFE) and P(VDF/TrFE)/C60are double peaks, respectively. It is also revealed from the C-V characteristic that the dipoles of P(VDF/TrFE) will simultaneously modulate the electric states of p- and n-type organic semiconductors(the depletion or accumulation) at the both interface of CuPc/P(VDF/TrFE)/C_60.
