Orbital Multiferroicity in Pentalayer Rhombohedral Graphene
Tonghang Han, Zhengguang Lu, Giovanni Scuri +8
Ferroic orders describe spontaneous polarization of spin, charge, and lattice degrees of freedom in materials. Materials featuring multiple ferroic orders, known as multiferroics,…
Perfect Coulomb drag and exciton transport in an excitonic insulator
Ruishi Qi, Andrew Y. Joe, Zuocheng Zhang +8
Strongly coupled two-dimensional electron-hole bilayers can give rise to novel quantum Bosonic states: electrons and holes in electrically isolated layers can pair into interlayer…
Perfect Coulomb drag in a dipolar excitonic insulator
Phuong X. Nguyen, Liguo Ma, Raghav Chaturvedi +4
Excitonic insulators (EIs), arising in semiconductors when the electron-hole binding energy exceeds the band gap, are a solid-state prototype for bosonic phases of matter. Unlike t…
Resonant band hybridization in alloyed transition metal dichalcogenide heterobilayers
Alessandro Catanzaro, Armando Genco, Charalambos Louca +13
Bandstructure engineering using alloying is widely utilised for achieving optimised performance in modern semiconductor devices. While alloying has been studied in monolayer transi…
Revealing the conduction band and pseudovector potential in 2D moiré semiconductors
Abigail J. Graham, Heonjoon Park, Paul V. Nguyen +12
Stacking monolayer semiconductors results in moiré patterns that host many correlated and topological electronic phenomena, but measurements of the basic electronic structure under…
Transport Anisotropy in One-dimensional Graphene Superlattice in the High Kronig-Penney Potential Limit
Tianlin Li, Hanying Chen, Kun Wang +5
One-dimensional graphene superlattice subjected to strong Kronig-Penney (KP) potential is promising for achieving electron lensing effect, while previous studies utilizing the modu…
