【Abstract】 It is proposed to use the signal intensity of modulation spectra for characterizing the nonlinear susceptibility of bulk semiconductor materials and microstructures.The principle and method of measurement are investigated.The large difference,as high as several orders of magnitude,between the signal intensities of electroreflectance spectra of quantum dots in doped glass with different cluster size is discussed.更多还原
