a An optical microscope image of the 8 \({\boldsymbol{\times }}\) 1 TRNG array and a schematic illustration of a part of the array. b The thermal circuit of the TRNG array. c The normalized heater energy (Eheater) and normalized heater energy per TRNG (Eheater/N) as a function of the array size (N). d The monobit test results of eight individual TRNGs obtained from the array. All passed the test in 10 μs. e The energy per bit and the TRN generation rate of the heater-embodying Mott-TRNG, fabricated on the three substrates, as a function of the array size. Symbols are experimentally obtained, and lines are modeled by calculation.
