A method for measuring carrier dynamics in micron-scale optoelectronic materials based on time-resolved microwave reflection is reported. Compared to a standard time-resolved photoluminescence approach, the authors show a 105 improvement in sensitivity when measuring lifetimes in a semiconductor pixel.
