However, recent experiments have shown that global differences persist even between same-material samples, which the standard mosaic framework does not account for. Here, we expand the mosaic framework by incorporating global differences in the densities of donor/acceptor sites. We develop\r\nan analytical model, backed by numerical simulations, that smoothly connects the global and deterministic charge transfer of different materials to the local and stochastic mosaic picture normally associated with identical materials. Going further, we extend our model to explain the effect of contact asymmetries during sliding, providing a plausible explanation for reversal of charging sign that has been observed experimentally."}],"external_id":{"arxiv":["2304.12861"],"isi":["001019565900002"]},"ddc":["537"],"publication_status":"published","doi":"10.1103/physrevmaterials.7.065601","_id":"13197","article_type":"original","file_date_updated":"2023-07-07T12:49:51Z","article_number":"065601","ec_funded":1,"keyword":["Physics and Astronomy (miscellaneous)","General Materials Science"],"date_created":"2023-07-07T12:48:01Z","citation":{"mla":"Grosjean, Galien M., and Scott R.
