We have fabricated In0.53Ga0.47As/AlAs/InP resonant tunneling diodes(RTDs) based on the air-bridge technology by using electron beam lithography processing.The epitaxial layers of the RTD were grown on semi-insulating(100) InP substrates by molecular beam epitaxy.RTDs with a peak current density of 24.6 kA/cm2 and a peak-to-valley current ratio of 8.6 at room temperature have been demonstrated.
