Abstract
Vertical transport I-V relations of type-I GaAs/AlAs superlattices wit h doped wells and weak coupling between wells at 77K were investigated with quasistatic and dynamic method. Spontaneous current oscillations are also investigated. The domain formation time 70 +/- 30 ns is dire ctly measured. By using discrete-tunneling model, the key parameters o f the relation between tunneling current and the bias between adjacent wells were quantitatively determined from the experimental data.
