Super-resolution Control of Individual Two-dimensional Quantum Emitters
Bosai Lyu, Valeria Vento, Ludivine Fausten +8
Localized interlayer excitons in semiconducting transition-metal dichalcogenide heterobilayers are quantum emitters with a static electric dipole moment, making them excellent nano…
Nanoscale electrostatic control in ferroelectric thin films through lattice chemistry
Ipek Efe, Alexander Vogel, William S. Huxter +7
Nanoscale electrostatic control of oxide interfaces enables physical phenomena and exotic functionalities beyond the realm of the bulk material. In technologically-relevant ferroel…
