            Abstract : 
In this paper, a new switching device having a p-type delta-oped sheet, ¿(p+), in the center of an InGaAs-GaAs quantum well is presented. An N-shaped negative-differential -resistance (NDR) phenomenon resulting from the resonant tunneling effect through the miniband under a proper anode-to-cathode voltage is observed. From the experimental results, it is seen that the temperature plays an important role in the device performances.
