Abstract

Multi-stack metal–insulator-metal (MIM) diodes of ultra-thin Ta<inf>2</inf>O<inf>5</inf>/Al<inf>2</inf>O<inf>3</inf> dielectrics are investigated by experiment and modelling. Tunnelling transport is modelled using transfer matrix (TMM) and Wentzel-Kramers-Brillouin (WKB) methods. Rectification for a triple dielectric layer device is shown to occur at a turn-on voltage (V<inf>ON</inf>) as low as 170 mV with a non-linearity of 3 and an asymmetry increasing from 2.2 at the V<inf>ON</inf> to over two orders of magnitude at 1 V.
