Conductivité négative différentielle (CND) et bistabilité en courant dans une structure tunnel résonnante ont été étudiées par l'effet oscillatoire dans le courant magnétotunnel avec J||B. Les mesures montrent que la bistabilité est associée avec l'accumulation et l'éjection de charge négative du puits. CND associé avec la deuxième sous-bande du puits est observée à plus grand voltage (~ 1 V). Les magnéto-oscillations indiquent la présence du tunnel séquentiel à cette région.Negative differential conductivity (NDC) and current bistability in a resonant tunnelling device are investigated by examining the oscillatory structure in the magnetotunnelling current for J ||B. The data support the conclusion that bistability is associated with build...
