Film-Depth-Dependent Light Absorption and Charge Transport for Polymer Electronics: A Case Study on Semiconductor/Insulator Blends by Plasma Etching

An easily accessible plasma etching approach is utilized to acquire film-depth-dependent light absorption spectra and 3D charge transport pathways in a polymer field-effect transistor, both with nanometer depth resolution. As an application of this study, depth-dependent optical and electronic properties of semiconductor/insulator blends films are synergically manipulated to increase optical transparency toward higher than 90% with simultaneously improved transistor performance.
