Abstract:We demonstrate a pulse generator based on a GaAs‐AlGaAs gated resonant tunneling diode (RTD). This is realized by integrating a third terminal, the gate, into the current path of a RTD. The gate consists of a 200 Å thick tungsten grating buried 300 Å above the RTD. This implementation allows for control of the current through the RTD. By integrating this device in parallel with an on‐chip inductance, a negative differential resistance (NDR) oscillator is formed. It is demonstrated that by using the gate to cha… Show more
