Electric field tunable negative differential resistance in zigzag phosphorene nanoribbons

A theoretical study on the line defects in β12-borophene: enhanced direct-current and alternating-current conductances

“…It is well known that the NDR effect is important for many functional nanodevices such as an electronically controlled oscillator. 60 Although the NDR effect was found in the line defect of the β 12 -borophene/χ 3 -borophene lateral heterostructure previously, 36 we suggest an alternative choice for realizing this effect. Under medium bias voltages, the DCs of some line defects keep nearly unchanged and can be approximately viewed as constants.…”
