Electrical switching behavior from ultrathin potential barrier ofself-assembly molecules tuned by interfacial charge trapping

The investigation of the self-assembly molecules of n -octyltrichlorosilane (OTS) as an ultrathin potential barrier in an organic two-terminal structure is presented. Electrical switching behavior with a large increase in current density is observed, and the mechanism of the electrical transition is mainly related to the OTS potential barrier tuned by charge trapping at the interface of OTS with the organic semiconductor layer. The switching behavior reveals the importance of the interfacial properties of self-assembly molecules in controlling the vertical charge transport.
