With a bulk plasma frequency in the terahertz range, extrinsic semiconductors may be employed to form composites with tailored dispersion characteristic for fabrication of passive components in the terahertz band. Computations have been performed to study the polarization process in nanoscale semiconducting plates and spheres, employing a transport formulation to account for space charge effects. Results reveal a frequency dependent dipole moment that is influenced by the carrier density when… CONTINUE READING
