[ 1 ] - بررسی اثرات شعاع داخلی و پهنا روی طیف انرژی و جریان پایا در حلقه های کوانتومی گرافینی هگزاگونال با لبه های زیگزاگ

  In this work, the effects of inner radius and width variation on energy spectrum and persistent current in hexagonal graphene quantum rings with zigzag edges have been studied by using the tight-binding model. Our investigation show that the energy spectra of these rings are grouped into subbands which each one consists of six coupled energy levels that separated by energy gaps. The pattern o...
