Quasicrystalline oxide interfaces by twisting SrTiO3 membranes
Shivasheesh Varshney, Sooho Choo, Huan Liu +34
Quasicrystals reveal that long-range order can exist without translational periodicity, but deterministic routes for designing strongly bonded quasicrystalline interfaces remain un…

Light-Driven Ultrafast Control of Time-Reversal Symmetry in SrTiO3
In Hyeok Choi, Sergei Urazhdin, Shivasheesh Varshney +3
Light-driven control of material symmetry enables the engineering of phenomena forbidden in equilibrium. Although electromagnetic fields have been used to break time-reversal symme…

Wafer-scale High-k SrTiO3 Dielectrics with Rational Barrier-layer Design for Low Leakage and High Charge Density
Majid Mohseni, Shivasheesh Varshney, Seung Gyo Jeong +3
High-k oxides such as SrTiO3 promise large capacitance, but their dielectric response is often limited by leakage currents due to reduced bandgaps. We show that introducing a thin…
