Kulumikizana kwamasinthidwe a atomiki, makamaka kuchuluka kwa kusokonezeka (DOD) kwa zolimba za amorphous ndi katundu, ndi gawo lofunikira la chidwi ndi sayansi yazinthu ndi sayansi yazinthu zofupikitsidwa chifukwa chazovuta kudziwa malo enieni a maatomu mumitundu itatu. zomangamanga1,2,3,4., Chinsinsi chakale, 5. Kuti izi zitheke, machitidwe a 2D amapereka chidziwitso chachinsinsi polola maatomu onse kuti awonetsedwe mwachindunji 6,7.Kuyerekeza kwachindunji kwa amorphous monolayer wa kaboni (AMC) wokulirapo ndi laser deposition amathetsa vuto la kasinthidwe ka atomiki, kuchirikiza kawonedwe kamakono ka crystallites mu zolimba zamagalasi kutengera chiphunzitso chachisawawa8.Komabe, ubale woyambitsa pakati pa kapangidwe ka atomiki ndi ma macroscopic sizikudziwika.Apa tikuwonetsa kuwongolera kosavuta kwa DOD ndi ma conductivity mu makanema owonda a AMC posintha kutentha kwa kukula.Makamaka, kutentha kwa pyrolysis ndikofunika kwambiri pakukula kwa ma AMC opangira ma AMC okhala ndi mitundu yosiyanasiyana ya kulumpha kwapakatikati (MRO), pomwe kukweza kutentha ndi 25 ° C kumapangitsa kuti ma AMC ataya MRO ndikukhala oteteza magetsi, ndikuwonjezera kukana kwa pepala. zinthu mu 109 nthawi.Kuphatikiza pakuwona ma nanocrystallite opotoka kwambiri ophatikizidwa mumanetiweki osasintha, ma electron microscopy atomic resolution adawonetsa kukhalapo / kusakhalapo kwa MRO ndi kachulukidwe ka nanocrystallite komwe kumadalira kutentha, magawo awiri amadongosolo omwe aperekedwa kuti afotokoze momveka bwino za DOD.Kuwerengera manambala kunakhazikitsa mapu a conductivity ngati ntchito ya magawo awiriwa, mwachindunji zokhudzana ndi microstructure kuzinthu zamagetsi.Ntchito yathu ikuyimira gawo lofunikira pakumvetsetsa mgwirizano pakati pa kapangidwe kake ndi katundu wa zida za amorphous pamlingo wofunikira ndikutsegula njira yamagetsi amagetsi pogwiritsa ntchito zida zamitundu iwiri.
Deta zonse zofunikira zomwe zapangidwa ndi/kapena zowunikidwa mu kafukufukuyu zikupezeka kuchokera kwa olembawo ngati apempha.
