... Figure 7.1: Ratio of the FDTD and exact phase speeds (c̃p /cp ) versus the discretization. Propagation in free space is assumed. Ideally the ratio would be unity for all discretizations. Courant numbers of 1/4, 1/2, and 3/4 are considered. Thus the phase speed in the FDTD grid is exactly what it is ...

... A P-N junction can be formed by taking a slice of Si of Ge crystal and doping it with trivalent impurity in one half and with a pentavalent impurity in the other half. The change carriers in the two regions move about in a random manner and will diffuse from a region of high concentration to a regio ...

... A more efficient alternative is to impose a uniform applied field inside the confinement without concerning the underlying charge distribution (implicitly determined by the Poisson equation). This approach was used in an interesting study of field effects on confined water by Vaitheesavaran et al.;5 ...
