Many-body effects have been investigated in the design of terahertz quantum well photon detectors. A large discrepancy between the theoretical and experimental photoresponse peak positions exist without considering the many-body interactions. The calculated results agree with the experimental data quantitatively with including the exchange-correlation and depolarization effects within the local density approximation. Our numerical results show that it is a must to consider the many-body interactions for designing the quantum well detectors for the terahertz region. [ABSTRACT FROM AUTHOR] |
