First observation of atomic rainbow from graphene

2026-06-17

We can observe a colourful rainbow in the sky when...

Schematisk bild som visar hur en ”atomär regnbåge” skapas och mäts. Till vänster representerar en lila sfär märkt ”Xe+” en positivt laddad xenonjon som rör sig mot ett tunt lager av enkellagersgrafen, ritat som ett hexagonalt bikakemönster av svarta atomer. Efter att ha passerat genom grafenet delas pilen upp i olika banor märkta ”experiment” och ”simulation”. Experimentella och simulerade färgkartor visas till höger. Den experimentella bilden innehåller ett cirkulärt mönster med en ljus mitt och en streckad linje som markerar en hexagon. Den simulerade bilden visar ett hexagonalt, stjärnliknande mönster med ljusa linjer.
