Tunneling density of states, correlation energy, and spin polarization in the fractional quantum Hall regime
Gaurav Chaudhary, Dmitry K. Efimkin, Allan H. MacDonald
We derive exact sum-rules that relate the tunneling density of states (TDOS) of spinful electrons in the fractional quantum Hall (FQH) regime to the spin-dependent many body ground…
Energy-resolved Photoconductivity Mapping in a Monolayer-bilayer WSe2 Lateral Heterostructure
Zhaodong Chu, Ali Han, Chao Lei +10
Vertical and lateral heterostructures of van der Waals materials provide tremendous flexibility for band structure engineering. Since electronic bands are sensitively affected by d…
Accurate Gap Determination in Monolayer and Bilayer Graphene/h-BN Moire Superlattices
Hakseong Kim, Nicolas Leconte, Bheema L. Chittari +5
High mobility single and few-layer graphene sheets are in many ways attractive as nanoelectronic circuit hosts but lack energy gaps, which are essential to the operation of field-e…
Moiré Excitons in Van der Waals Heterostructures
Kha Tran, Galan Moody, Fengcheng Wu +19
In van der Waals (vdW) heterostructures formed by stacking two monolayer semiconductors, lattice mismatch or rotational misalignment introduces an in-plane moiré superlattice. Whil…
Topological insulators in twisted transition metal dichalcogenide homobilayers
Fengcheng Wu, Timothy Lovorn, Emanuel Tutuc +2
We show that moiré bands of twisted homobilayers can be topologically nontrivial, and illustrate the tendency by studying valence band states in valleys of twisted bilayer…
Chiral transport and electronic correlations in surface states of HfNiSn single crystals
L. Steinke, J. J. Kistner-Morris, T. F. Lovorn +9
In most topological insulators, the valence and conduction band appear in reverse or inverted order compared to an equivalent insulator with isolated atoms. Here, we explore a diff…
