N2 - In this paper, we present a new self-switching diode (SSD) realized with a two-dimensional semiconductor hexagonal boron carbon-nitrogen (hBCN) monolayer. Channel length and width are 4.5 nm and 1.23 nm respectively. The device operation is simulated based on the Extended Huckel method and Nonequilibrium Green’s Function (NEGF) Formalism. The simulation results indicate non-linear I-V characteristics of the nano-diode and a current rectification ratio near 11250 that is higher than previous SSD structures reported before. Also, the effects of channel width on the electrical characteristics of SSDs are investigated. It can be found that the bandgap value of hBCN plays an important role in the modulation of current in the channel. Transmission pathways are provided under reverse and forward biases to show channel opening and pinch-off conditions. The results indicate that hBCN is a promising material for the realization of self-switching diodes (SSDs).
