Resonant Interband Tunnel Diodes (RITD) with device sizes ranging from r=20μm to r=50nm (mask defined radii) were manufactured using an e-beam lithography and dry-etch process. The peak to valley current-ratio (PVCR) and peak current density (jpeak) of the devices were measured. The devices showed high series resistance, and currents and PVCR did not scale in a predictable pattern.
