主 题:bilayer graphene quantum dots rotational stacking faults first-principles calculation
摘 要:Bilayer graphene quantum dots with rotational stacking faults(RSFs) having different rotational angles were *** the first-principles calculation, we determined that these stacking faults could quantitatively modulate the magnetism and the distribution of spin and energy levels in the electronic structures of the *** addition, by examining the spatial distribution of unpaired spins and Bader charge analysis, we found that the main source of magnetic moment originated from the edge atoms of the quantum *** research results can potentially provide a new path for producing all-carbon nanodevices with different electrical and magnetic properties.
