High‐Performance Pentacene‐Based Field‐Effect Transistor Memory Using the Electrets of Polymer Blends

Abstract: Organic field-effect transistor (OFET) memory based on pentacene has attracted a lot of attentions due to its promising prospect of application in flexible electronics, while the high programming/erasing (P/E) gate voltages due to the existence of hole barrier at pentacene/polymer interface leaves great challenges for its commercial applications. A high-performance pentacenebased OFET nonvolatile memory (ONVM) with polymer blends is reported here as the charge-trapping layer containing poly(2-vinyl naphthalene… Show more

“…When two successive negative gate voltage pulses are applied, the current after the second pulse is smaller than the current after the first pulse (Figure S17c, Supporting Information). [8,46,69] The changes of inhibitory postsynaptic current after stimulation with different numbers of negative gate pulses are shown in Figure 6e, IPSC stimulated by 50 consecutive pulses was much lower compared to that under two consecutive pulses, which is similar to short-term depression (STD) transfer to long-term depression (LTD). The synaptic performance of the device with unetched PS is shown in Figure S18, Supporting Information.…”

“…[22] Therefore, electrets are formed by injecting holes into the polymer's layer. [20,[44][45][46][47] Part of the injected charges are captured in a deeper energy level, and when the gate-bias stress is removed, the injected charges can still be maintained in PS for a long time, stably modulating the operation of OFETs. [48][49] Moreover, with the increase of plasma treating time, the transfer curve moves to the negative direction gradually under the negative gate-bias stress of 1 ms (Figure S6, Supporting Information), which proves that the hole injection capability of the device is improved.…”

“…Organic small molecule pentacene (C 22 H 14 ) has witnessed successional breakthroughs in organic thin film transistors (TFTs) [42][43][44] due to its advantages of high hole mobility, considerably long carrier diffusion length (40.55 mm), and agile preparation. 45 The CsPbCl 3 -pentacene hybrid structure could thus potentially enhance the optoelectronic properties in CsPbCl 3 based photodetectors.…”
