Resonant tunneling device of high power output and wide operation region.

What is it about?

The peak current density reaches 2.43 KA/cm2 as the i-AlAs barriers reaches 5 nm thickness. The optimal thickness of barrier layers should be selected at 4 nm thickness to obtain the highest PVCR value (about 4270).

Why is it important?

Highest current density and PVCR are obtained in this resaerch via the suitable design of device structure.

Other compound materials and device designs might be also selected to fabricate the devices of well resonant tunneling properties applied in microwave transmission.
