Charge extraction by linearly increasing

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.

The extraction ability of neutral organophosphorus compounds closely related to the charge density of phosphoryl oxygen (qo) and phosphorus atom(qp). It was found that the distribution ratio of cerium enhanced as the qo and qp values was increased. Meanwhile a linear free energy relationship exists between the 2A.i values and the Kabachnik constant for substituents of phosphorus compounds. As estimated by least squares method, an empirical equation v° =-3.84+0.1682Ai was deduced...
