Measurement of the autocorrelation function of a cathodoluminescence signal: Characteristics and applications in nanosecond time resolved and nanometer spatially resolved experiment

In this presentation we show that the autocorrelation function of the cathodoluminescence signal (CL-g
⁽²⁾
(τ)) can be different from the photoluminescence PL-g
⁽²⁾
(τ) showing a huge nanosecond bunching effect g
⁽²⁾
(0) >> 1, allowing to retrieve emitters lifetime at nanometer scale.
