Abstract

A switching device, with a p-type delta-doped sheet in the center of an InGaAs-GaAs quantum well, has been fabricated and demonstrated. An N-shaped negative-differential-resistance phenomenon resulting from the resonant-tunneling effect through the miniband is observed in the current-voltage measurement. From the experimental results, it is seen that the temperature plays an important role in device operation. The influences of temperature upon the peak-current voltage, valley-current voltage, peak-current density, and valley-current density are studied and discussed.
