WebIn addition, the ADA polymer acts as a passivation interlayer that impacts on the hysteresis of J-V curves as well (Figure 3f and S3). The addition of a thin layer of the adamantane polymer at the interface reduces the hysteresis index, HI,[23] by more than half (i.e., an average HI ∼ 0.13 and ∼ 0.05 for reference and ADA-5nm, respectively). WebIII-V semiconductor devices typically use structures grown layer-by-layer and require passivation of sidewalls by vertical etching to reduce leakage current. The passivation is conventionally achieved by sealing the sidewalls using polymer and the polymer needs to be planarized by polymer etch-back method to device top for metal interconnection.
