Abstract
In this letter, we show a novel GaAs delta-doping induced triangle-like double-barrier quantum well diode. The double barriers are induced by the δn + -i-δp + -i-δn + structure grown by delta-doping technique. The current-voltage characteristics exhibits two different types of negative differential resistance (NDR) at low and high bias, respectively. At low bias, N-type NDRs with peak-to-valley ratio 1.5 were observed due to resonant tunneling effect. An S-type NDR existed at high bias. This results from impact ionization in high electric field.
