Charge extraction by linearly increasing voltage

FIGURE 10.11 Experimental setups and the typical response of the time-of-flight and the charge extraction by linearly increasing voltage technique (CELIV). 

Charge extraction by linearly increasing voltage (CELIV) [15,16] is another important technique to extract the drift mobility of transistors however it is applicable to organic LEDs and provides information about mobility in the perpendicular direction similar to optical time-of-flight.
