Prediction of the Bandgap of a Core-Shell Microsphere via Light Intensity Fluctuations
Figure 3
Source functions versus for a single-layer microsphere of 500 nm radius, the crystal size of 3.0 nm, and many different wavelengths. (a) For the wavelengths from 410 nm to 460 nm. (b) For the wavelengths from 580 nm to 660 nm. Other wavelengths between 100 and 1000 nm were treated, but they are not shown here because they do not produce fluctuations. The number of surface peripheral elements was 525. The refractive index on the unit cell edge was chosen to be 2.80 i0.01. The abscissa tic corresponds to a point on the particle surface opposite the incident light (in the forward scattering direction) and +1 corresponds to the point nearest the incident light source (in the back scattering direction).
