웹2024년 4월 25일 · The moiré pattern restricts the electronic states of transition metal bilayers, thus extending the concept of the magic angle found in twisted bilayer graphene to semiconductors. Here, we have studied the electronic structure of the twisted bilayer WTe2 using first-principle calculations. Our result shows that a twist significantly changes the … 웹The bandgap generally moves to higher frequencies and becomes narrower when more kirigami bits are in the state (1). However, if the total number of (1) bits stays the same, the bandgap would jump to different frequencies as we change the sequence of these (1) bits, elucidating the rich programmability of the bandgaps in kirigami.
