ABSTRACT
We present a generalized Einstein relation analysis, applicable for disordered semiconductors with exponential distributions of tail states and square-root distributions of band states. We find that there are substantial deviations from the traditional nondegenerate form of this relation, these deviations arising as a consequence of the degeneracy of the occupation statistics within disordered semiconductors. We use these results to account for some hydrogenated amorphous silicon experimental results. © 2003 American Institute of Physics.

    In this study, a new second order all-pass filter is synthesized in the square-root domain by using the state-space method. The proposed second order all-pass filter is constituted by current mirrors, current sources, current-mode square-root circuits and capacitors. The pole frequency of the...
