Abstract:

The paper deals with the theoretical investigation of intrasubband plasmons in weakly disordered array of quantum wires QWs consisting of finite number of QWs. The array of QWs is characterized by the fact that the density of electrons of one defect QW is different from that of other QWs. It is shown that the amount of plasmon modes in weakly disordered array of QWs is equal to the number of QWs in array. The existence of a local plasmon mode, whose properties differ from those of usual modes is found. We point out that the local plasmon mode spectrum is slightly sensitive to the position of defectthe in array. At the same time the spectrum of usual plasmon modes is shown to be very sensitive to the position of defect QW.
