Objective: To study the dynamics of magneto-resistance in organic diodes
Approach: Measure electronic transport and magneto-transport of organic diodes as a function of frequency with an applied magnetic field using admittance spectroscopy
Preliminary Results & Significance:
The magneto-conductance (inverse of resistance) of a conducting polymer-based diode was measured as a function of frequency and bias voltage. The observed properties show that the relevant underlying processes occur on a timescale of ~100 ns.
Fig. 1: The frequency response of magneto-conductance, ΔG/G, of an organic conducting polymer-based bipolar diode measured at room temperature and with an applied magnetic field. The inset shows the magneto-conductance at f=1 Hz as a function of the bias voltage.
