Terahertz absorption in a double quantum well system under a magnetic field

Conference Paper


Abstract


  • The absorption of electromagnetic (EM) waves in a double well structure is calculated in the terahertz frequency region. It is found that at frequencies higher than the cyclotron frequencies of electrons and holes, the EM absorption exhibits oscillatory behavior. The maxima in the absorption coefficient correspond to a situation where the photon energy is approximately the sum of the energies of the electron pair and the hole pair which are simultaneously excited by the radiation field. © 1998 Elsevier Science B.V.
