We report repeatable AlGaN/GaN resonant tunneling diodes (RTDs) grown on a sapphire substrate by metal organic chemical vapor deposition. The RTDs exhibit clear negative differential resistance at low temperature in both bias directions. Peak-to-valley current ratios of 1.4 and 1.08 and peak current densities of 6 kA/cm2 and 0.65 kA/cm2 are extracted at 6.5 K for forward and reverse bias, respectively. The polarization fields in III-nitrides are found to affect the diode electrical behaviors by modulating the symmetry of the two barriers and altering the thickness of the depletion region, which eventually triggers asymmetric resonant tunneling transport.
