MEASUREMENT OF THE AMBIPOLAR DIFFUSION COEFFICIENT USING TIME-DELAYED FOUR-WAVE MIXING WITH INCOHERENT LIGHT
用非相干光时间延迟四波混频测量二极扩散系数

This paper reports the theoretical calculation of the ambipolar diffusion coefficient in TDFWM-IL. We have obtained the ambipolar diffuion coefficient Da= 0.3cm2/s for CdS:Cu and compared with measured results for PbS ultrafine particles.
