Modeling and RF analysis of silicon inter-band tunnel diode with THz cut-off frequency

We demonstrated RF analysis framework based on tunnel velocity model for Si IBT diodes with ultra-thin tunnel barriers. Microwave and sub-millimeter wave properties of the non-linear NDR characteristics have been investigated in a numerical way with various structural design. The intrinsic cut-off frequency can be obtained up to THz-level for highly doped nanoscale Si tunnel junctions.
