Schottky Biristor: A Metal-Semiconductor–Metal Bistable Resistor

In this brief, we report a novel metal-semiconductor-metal-based bistable resistor, called the Schottky biristor, whose performance is superior to the existing bipolar junction transistor-based biristors. The proposed device can be realized by joining symmetrical Schottky contacts back to back. Apart from being free of the thermal budgets involved in the fabrication of p-n junctions in a biristor, the Schottky biristor also has much lower latch voltages (latch-up voltage of 1.62 V and latch-down voltage of 1.18 V) and a reasonable latch window (0.44 V) as demonstrated by our simulation results.
