Abstract :
An n-InAsSb/p-GaSb tunnel junction for intra-device contacts with an extremely low contact resistivity of 2.4×10-6 Ω cm2 is reported. Both sides of the junction were doped with silicon, using the amphoteric nature of the dopant for n- and p-type doping. This should provide long-term stability of the device.
