Development of an novelapproach for the simulation of nanodevices using FDTD

A new way for the simulation of nano-devices is presented, which consists of Schrodinger´s equation, time dependent scalar and vector potential equations derived from Maxwell´s equations using Lorenz gauge. For analysis the finite difference time domain (FDTD) method is applied to these equations. To validate the method a two-dimensional semiconductor nanocavity is considered and numerical results are compared with those of the analytical results.
