Fig. 1: Schematic plot of zigzag honeycomb nanoribbons with side potential.
From: Modulation of antichiral edge states in zigzag honeycomb nanoribbons by side potentials
The side potentials include potential field U1,2, staggered potential field EZ1,2, and exchange field M1,2 along the boundaries. Ny is defined by the number of carbon atoms along the width direction, and W = 8 is the width of the side potentials.
