Tooj Liab Ntawv Nyiaj Rau Graphene

Graphene yog ib yam khoom tshiab uas cov pa roj carbon atoms txuas nrog los ntawm sp² hybridization raug sib dhos ua ke rau hauv ib txheej ntawm ob-seem honeycomb lattice qauv. Nrog rau cov khoom siv optical, hluav taws xob, thiab mechanical zoo heev, graphene muaj kev cog lus tseem ceeb rau kev siv hauv cov ntaub ntawv science, micro thiab nano processing, lub zog, biomedicine, thiab kev xa tshuaj, thiab suav hais tias yog cov khoom siv hloov pauv ntawm yav tom ntej. Chemical vapor deposition (CVD) yog ib qho ntawm cov txheej txheem siv ntau tshaj plaws rau kev tswj hwm kev tsim khoom ntawm graphene loj. Nws lub hauv paus ntsiab lus tseem ceeb yog kom tau txais graphene los ntawm kev tso nws rau ntawm qhov chaw ntawm cov hlau ua substrate thiab catalyst, thiab dhau ib qho nyiaj ntawm cov pa roj carbon precursor thiab hydrogen roj hauv qhov chaw kub siab, uas cuam tshuam nrog ib leeg. Cov ntawv ci tooj liab rau graphene tsim los ntawm CIVEN METAL muaj cov yam ntxwv ntawm kev ntshiab siab, kev ruaj khov zoo, wafer sib xws thiab tiaj tiaj, uas yog cov khoom siv substrate zoo tagnrho hauv CVD txheej txheem.
