Standard hardware random number generators often use quantum mechanical phenomena or thermal noise to produce bit streams of random, but often biased, origin. In contrast, colloidal self-assembly of billions of particles on 1 cm2 can assure bias-free, heterogeneous particle sequences to be employed as bits in a hardware random number generator.
Utilizing template-assisted colloidal self-assembly of two different particle types (Au spheres and Ag spheres), heterogeneous single particle lines are assembled and subsequently analyzed via electron microscopy. Statistical evaluation shows that Ag and Au do not assemble in any way preferential to any particle type, generating random distributions only dependent on employed Ag/Au particle share.
