Direct spatiotemporal imaging of carriers reveals a long-lived bulk photovoltaic mechanism
Saptam Ganguly, Sebin Varghese, Aaron M. Schankler +6
The bulk photovoltaic effect (BPVE), a manifestation of broken centrosymmetry, has attracted interest as a probe of the symmetry and quantum geometry of materials, and for use in p…
Reconfigurable, non-volatile control of optical anisotropy in ReS2 via ferroelectric gating
Mahfujur Rahaman, Seunguk Song, Aaliyah C. Khan +8
Electrically tunable linear dichroism (LD) with non-volatile properties represents a critical yet elusive feature for next-generation integrated photonic elements in practical devi…
Ferroelectric Fractals: Switching Mechanism of Wurtzite AlN
Drew Behrendt, Atanu Samanta, Andrew M. Rappe
The advent of wurtzite ferroelectrics is enabling a new generation of ferroelectric devices for computer memory that has the potential to bypass the von Neumann bottleneck, due to…
Domain wall reactions in multiple-order parameter ferroelectrics
Songsong Zhou, Shihan Qin, Andrew M. Rappe
The motion of domain walls is crucial for ferroelectric switching. Conventionally, the switching dynamics is believed to be determined by the motion of one or a few low-energy doma…
