Wavelength-Resolved Control of Photovoltaic Screening and Defect-Mediated Doping in Photo-Ferroelectric/Graphene Devices

Krishna Prasad Maity, Mohd Uvais, Jean-Francois Dayen +3

Ferroelectrics enable large charge doping of two-dimensional overlayers, but the coexistence of switching and nonswitching charge dynamics complicate electro-optical analysis. Here…

Disorder-driven magnetic duality in the spin- $\frac{1}{2}$ system ktenasite, Cu $_{2.7}$ Zn $_{2.3}$ (SO $_{4}$ ) $_{2}$ (OH) $_{6} \cdot$ 6H $_{2}$ O

Kaushick K. Parui, Anton A. Kulbakov, Roman Gumeniuk +8

Disorder in frustrated quantum systems can critically influence their magnetic ground states and drive exotic correlated behavior. In the $S = \frac{1}{2}$ system ktenasite, Cu$_\t…
