Rolling the Dice with Light Competition: Introducing a True Random Number Generator Powered by Photo‐Induced Polarity Current (Adv. Mater. 14/2025)
True Random Number Generator In article number 2419579, Hocheon Yoo and co-workers present arc discharge light-induced true random number generator (ALTRNG), using a bipolar photo-responsive photodetector to generate random bits through unpredictable arc discharge illumination. Validated by 15 National Institute of Standards and Technology (NIST) tests, ALTRNG produces highly random bit streams and, with a 2-kbps readout circuit, enables wireless random number transmission for secure password systems and artificial X-ray imaging.
