Ukuhlotshaniswa kokuhlelwa kwe-athomu, ikakhulukazi i-degree of disorder (DOD) yezinto eziqinile ze-amorphous ezinezakhiwo, kuyindawo ebalulekile yesithakazelo kwisayensi yezinto ezibonakalayo kanye ne-condesed matter physics ngenxa yobunzima bokunquma ukuma okuqondile kwama-athomu ku-three-dimensional. izakhiwo1,2,3,4., Imfihlakalo endala, 5. Kuze kube manje, izinhlelo ze-2D zinikeza ukuqonda ngemfihlakalo ngokuvumela wonke ama-athomu ukuthi aboniswe ngokuqondile 6,7.Ukuthwebula okuqondile kwe-amorphous monolayer ye-carbon (AMC) ekhuliswe nge-laser deposition kuxazulula inkinga yokucushwa kwe-athomu, kusekela umbono wesimanje wamakristalu ezintweni eziqinile eziyingilazi ngokusekelwe kumbono wenethiwekhi okungahleliwe8.Kodwa-ke, ubudlelwano bembangela phakathi kwesakhiwo sesikali se-athomu kanye nezakhiwo ze-macroscopic kuhlala kungacaci.Lapha sibika ukushuna okulula kwe-DOD kanye nokusebenza kumafilimu amancanyana e-AMC ngokushintsha izinga lokushisa lokukhula.Ikakhulukazi, izinga lokushisa le-pyrolysis threshold liyisihluthulelo sokukhula kwama-AMCs ane-variable range of medium order jumps (MRO), kuyilapho ukuphakamisa izinga lokushisa ngo-25 ° C kubangela ukuthi ama-AMC alahlekelwe i-MRO futhi abe i-insulating kagesi, okwandisa ukumelana kweshidi. impahla izikhathi ezingu-109.Ngaphezu kokubona ngeso lengqondo ama-nanocrystallite ahlanekezelwe kakhulu ashumekwe kumanethiwekhi angahleliwe aqhubekayo, i-athomu encane ye-electron microscopy yembula ukuba khona/ukungabikho kwe-MRO kanye nokuminyana kwe-nanocrystallite okuncike kuzinga lokushisa, imingcele yokuhleleka emibili ehlongozwayo ukuze kuchazwe kabanzi nge-DOD.Izibalo zezinombolo zisungule imephu ye-conductivity njengomsebenzi walawa mapharamitha amabili, ahlobanisa ngokuqondile i-microstructure nezakhiwo zikagesi.Umsebenzi wethu umele isinyathelo esibalulekile ekuqondeni ubudlelwano phakathi kwesakhiwo kanye nezakhiwo zezinto ze-amorphous ezingeni eliyisisekelo futhi uvula indlela yemishini kagesi esebenzisa izinto ze-amorphous ezinezinhlangothi ezimbili.
Yonke imininingwane efanele ekhiqizwe kanye/noma ehlaziywe kulolu cwaningo iyatholakala kubabhali abafanele uma kunesicelo esifanele.
