Con esta técnica, el laboratorio puede observar y manipular ese recorrido en escalas de nanómetros y femtosegundos. Para la electrónica del futuro, entender y dirigir ese flujo es el paso previo a diseñar chips más rápidos y eficientes, algo que a la larga puede llegar a los dispositivos que usamos todos los días.","quienFirma":"Technion - Instituto Tecnológico de Israel","confianza":"preprint","consulta":null},"sello":{"hash":"0546d847fdc7d8ddd650a7e35612c85d6607b757b657a184cf2da9f7c775d0df","sello":"613557999868bf65cee33d6883bcba67022b6adddfdabfa04b4ba071e04febe8","beacon":{"drand":{"cadena":"8990e7a9aaed2ffed73dbd7092123d6f289930540d7651336225dc172e51b2ce","ronda":6577069,"aleatorio":"f3cdaf5c6faa11642c2892b64c9d25ca7e52ee1ed52e1dd87af4cc6b729531e2","tiempo":"2026-10-23T08:11:30.000Z"},"nist":{"cadena":2,"pulso":1995734,"salida":"8B73B13DEE1890CB134E89B52FB9A1533693BA5B0A94B792B9C7771272BBB28DE63B29FA9D784854C2AFD3A4D5AE2B44A8D094B117C2592B48BE8D929BCD87A5","tiempo":"2026-10-23T08:11:00.000Z"},"noAntes":"2026-10-23T08:11:30.000Z"},"verificacion":{"drand":true,"nist":true},"tsa":{"time":"Oct 23 08:12:06 2026 GMT","provider":"freetsa.org","sobre":"sello"},"original":{"titulo":"Light-based method enables precise control of ultrafast electron flow in a scanning tunneling microscope","descripcion":"What would it take to watch an electron move through a material? Researchers would need to see individual atoms and capture an electron's motion at incredibly short timescales.
