A metal/oxide tunneling transistor

Abstract: We have fabricated a nanometer-scale transistor that operates by using a gate field to modulate the transmission of electrons through a lateral metal/oxide tunnel barrier. Our initial devices have a 30-nm-wide lateral Nb/NbOx tunnel junction on top of a planar Al2O3/Al buried gate. We observe effective modulation of the source–drain current with gate bias at room temperature with negligible gate leakage current. We identify the materials issues that currently limit the device performance, and we offer directio… Show more

“…The barriers between dots in this system are typically very thin slices of oxide. While there have been some promising experiments involving the modulation of such barriers [8], in general it is much harder to accomplish than in the semiconductor case. In this paper we demonstrate a scheme for quasi-adiabatic switching of metallic QCA cells.…”
