abstract = {The development of the internet-of-things requires cheap, light, small and reliable true random number
generator (TRNG) circuits to encrypt the data—generated by objects or humans—before transmitting
them. However, all current solutions consume too much power and require a relatively large battery, hindering
the integration of TRNG circuits on most objects. Here we fabricated a TRNG circuit by exploiting
stable random telegraph noise (RTN) current signals produced by memristors made of two-dimensional
(2D) multi-layered hexagonal boron nitride (h-BN) grown by chemical vapor deposition and coupled with
inkjet-printed Ag electrodes. When biased at small constant voltages (≤70 mV), the Ag/h-BN/Ag memristors
exhibit RTN signals with very low power consumption (∼5.25 nW) and a relatively high current on/off
ratio (∼2) for long periods (>1 hour). We constructed TRNG circuits connecting an h-BN memristor to a
small, light and cheap commercial microcontroller, producing a highly-stochastic, high-throughput signal
(up to 7.8 Mbit s−1) even if the RTN at the input gets interrupted for long times up to 20 s, and if the stochasticity
of the RTN signal is reduced. Our study presents the first full hardware implementation of 2Dmaterial-
based TRNGs, enabled by the unique stability and figures of merit of the RTN signals in h-BN
based memristors.},
