Origin of magic angles in twisted bilayer graphene: The magic ring
Wei-Chen Wang, Feng-Wu Chen, Kuan-Sen Lin +3
The unexpected discovery of superconductivity and strong electron correlation in twisted bilayer graphene (TBG), a system containing only sp electrons, is considered as one of the…
On the local aspect of valleytronics
Zheng-Han Huang, Feng-Wu Chen, Yu-Shu G. Wu
Valley magnetic moments play a crucial role in valleytronics in 2D hexagonal materials. Traditionally, based on studies of quantum states in homogeneous bulks, it is widely believe…
All-electrical valley filtering in graphene systems (II): Numerical study of electron transport in valley valves
Jia-Huei Jiang, Ning-Yuan Lue, Feng-Wu Chen +1
This work performs a numerical study of electron transport through the fundamental logic gate in valleytronics - a valley valve consisting of two or increasing number of valley fil…
All-electrical valley filtering in graphene systems (I): A path to integrated electro-valleytronics
Feng-Wu Chen, Nin-Yuan Lue, Mei-Yin Chou +1
Probing and controlling the valley degree of freedom in graphene systems by transport measurements has been a major challenge to fully exploit the unique properties of this two-dim…
Valley field mechanics: a local perspective beyond valley flavor
Feng-Wu Chen, Zheng-Han Huang, Yu-Shu G. Wu
Valleytronics in 2D materials - primarily graphene and transition metal dichalcogenides is rooted in the existence of valley flavor but extends far out to the rich dimension of loc…
Theory of field-modulated spin-valley-orbital pseudospin physics
Feng-Wu Chen, Yu-Shu Wu
Pioneering studies in transition metal dichalcogenides have demonstrated convincingly the co-existence of multiple angular momentum degrees of freedom -- of spin (1/2 $s_z = \pm 1/…
Theory of valley-dependent transport in graphene-based lateral quantum structures
Feng-Wu Chen, Mei-Yin Chou, Yiing-Rei Chen +1
Modulation of electronic states in two-dimensional (2D) materials can be achieved by using in-plane variations of the band gap or the average potential in lateral quantum structure…
