| Abstract: | Current-Voltage Characteristics in three-quantum-well superlattice units are studiea by numerically solving the nonequilibrium Wigner Function Equation. Parameter changes of three-quantum-well obviously affect its Current-Voltage Characteristics. The numerical results provide theoretic attestation for farther experimental research to a certain extent and useful reference informations for design and manufacture. |
