Extracting electron hole mobility by analyzing the current frequency space via NLIS

Conference Year

January 2020

Abstract

Through the use of Nonlinear Impedance Spectroscopy (NLIS) and using Fourier analysis of the measured higher harmonic current due to an AC voltage signal passed through an organic semiconductor we can approximate the electron-hole recombination and the space charge effects in the bulk organic semiconductor device. In our case, we are looking at MIS capacitors and PH diodes in particular. Characterizing the higher harmonic current response to effectively use Nonlinear Impedance Spectroscopy to extract the mobility of the device(s) over a range of applied AC frequencies.
