The electronic transport characteristics of hybridized hexagon beryllium sulfide and graphene nanoribbons

Hybridized Z-BexSyCz (x+y+z=16) systems connected by zigzag beryllium-sulfide (BeS) and graphene nanoribbons are theoretically designed, and their electronic transport characteristics are explored by first-principles approach. For the hybridized systems with unequal number of x and y, i.e. z is an odd number, an exceptional negative differential resistance (NDR) property occurs. However, for the hybridized systems including an even number of zigzag carbon chains, namely x equal to y, an interesting current-limited behavior happens. Meanwhile, the NDR phenomenon disappears. The spin transport properties of these hybridized Z-BexSyCz systems with parallel magnetism configuration also reveal the above odd–even dependence conductance behavior.
