Nanostructured THz Gunn diode using integration of the side-contact and field-plate technologies

This paper deals with a nanostructured THz Gunn diode with a patch antenna using the concepts of the side-contact and field-plate technologies to simplify the design for a small effective diode height of few 100 nm with uniform field distribution for high voltage oscillation instead of an external RLC resonator. A stable negative differential resistance has been measured.
