Ulungelelwaniso lolungelelwaniso lweathom, ngakumbi inqanaba lokuphazamiseka (i-DOD) ye-amorphous solids kunye neepropathi, yindawo ebalulekileyo yomdla kwisayensi yezixhobo kunye ne-fiziksi yento econdensed ngenxa yobunzima bokumisela ezona ndawo zichanekileyo ze-athomu kumacala amathathu. izakhiwo1,2,3,4., Imfihlelo endala, 5. Kule njongo, iinkqubo ze-2D zibonelela ngengqiqo kwimfihlelo ngokuvumela zonke ii-athomu ukuba ziboniswe ngokuthe ngqo kwi-6,7.Imifanekiso ethe ngqo ye-amorphous monolayer yekhabhoni (AMC) ekhuliswe yi-laser deposition isombulula ingxaki yokwakheka kweathom, ixhasa imbono yanamhlanje yeekristale kwizinto eziqinileyo zeglasi esekwe kwithiyori yenethiwekhi engacwangciswanga8.Nangona kunjalo, ubudlelwane be-causal phakathi kolwakhiwo lwesikali se-atom kunye neempawu ze-macroscopic zihlala zingacacanga.Apha sinika ingxelo yokulungisa ngokulula kwe-DOD kunye nokuqhutywa kweefilimu ezibhityileyo ze-AMC ngokuguqula ubushushu bokukhula.Ngokukodwa, i-pyrolysis threshold iqondo lokushisa lingundoqo ekukhuleni kwe-AMCs eziqhubayo kunye noluhlu oluguquguqukayo lwe-medium order jumps (MRO), ngelixa ukunyusa ubushushu nge-25 ° C kubangela ukuba i-AMCs ilahlekelwe yi-MRO kwaye ibe yi-insulating yombane, ukwandisa ukuchasana kwephepha. izinto eziphathekayo ngamaxesha angama-109.Ukongezelela ekuboneni i-nanocrystallites egqwethekileyo kakhulu efakwe kuthungelwano olungahleliwe oluqhubekayo, isisombululo se-athomu ye-electron microscopy ibonise ubukho / ukungabikho kwe-MRO kunye noxinzelelo lwe-nanocrystallite oluxhomekeke kwiqondo lokushisa, iiparitha ezimbini zomyalelo ezicetywayo kwinkcazo ebanzi ye-DOD.Ubalo lwamanani lusekwe imephu ye-conductivity njengomsebenzi wale miqathango mibini, ehambelana ngqo ne-microstructure kwiipropati zombane.Umsebenzi wethu umele inyathelo elibalulekileyo ekuqondeni ubudlelwane phakathi kwesakhiwo kunye neepropathi zezixhobo ze-amorphous kwinqanaba elisisiseko kwaye uvula indlela yezixhobo zombane usebenzisa izinto ezimbini-dimensional amorphous materials.
