Ferroelectric hysteresis in singly aligned graphene-hBN moiré superlattices
Bao Q. Tu, Tanweer Ahmed, Garen Avedissian +7
Ferroelectric materials have the unique ability to maintain an electric polarization which can be reversed under an external applied electric field. This property makes them valuab…
Second-Order Conductivity Probes a Cascade of Singularities in a Moiré Superlattice
Tanweer Ahmed, Bao Q. Tu, Kenji Watanabe +4
Systems lacking inversion symmetry inherently demonstrate a nonlinear electrical response (NLER) to an applied electric bias, emerging through extrinsic mechanisms. This response i…
Detecting Lifshitz Transitions Using Nonlinear Conductivity in Bilayer Graphene
Tanweer Ahmed, Harsh Varshney, Bao Q. Tu +6
The second-order nonlinear electrical response (NLER) is an intrinsic property of inversion symmetry-broken systems which can provide deep insights into the electronic band structu…
Unveiling intrinsic bulk photovoltaic effect in atomically thin ReS2
Maria Ramos, Tanweer Ahmed, Bao Q. Tu +10
The bulk photovoltaic effect (BPVE) offers a promising avenue to surpass the efficiency limitations of current solar cell technology. However, disentangling intrinsic and extrinsic…
