Electromagnetic absorption in an electron-hole double-layer system in a magnetic field

Journal Article


Abstract


  • The high-frequency magnetoconductivity for a double-layer electron-hole system is calculated at finite temperature. The formalism rests on the temperature Green's function and Kubo's formula for conductivity. It is found that at frequencies higher than the cyclotron frequencies of electrons and holes, the frequency-dependent electromagnetic absorption exhibits oscillatory behaviour. 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.
