Time-resolved microwave conductivity measurements: TRMC measurements were performed by mounting the samples in a microwave cavity cell and placing within a setup similar to the one described. A voltage controlled oscillator (SiversIMA VO3262X) generated the microwaves where K is the sensitivity factor derived from the resonance characteristics of the cavity and the dielectric properties of the medium. From the experimentally observed change in the photoconductance, the product of the charge carrier generation yield (𝜙𝜙) and the sum of electron and hole mobilities (Σμ) can be obtained
