Correlative mapping of local hysteresis properties in VO
Melissa Alzate Banguero, Sayan Basak, Nicolas Raymond +6
We have developed a new optical microscopy technique able to track micron-sized surface clusters as temperature is varied. Potential candidates for study include phase separated me…
Imaging the itinerant-to-localized transmutation of electrons across the metal-to-insulator transition in VO
Maximilian Thees, Min-Han Lee, Rosa Luca Bouwmeester +14
In solids, strong repulsion between electrons can inhibit their movement and result in a "Mott" metal-to-insulator transition (MIT), a fundamental phenomenon whose understanding ha…
Transport in a Single Self-Doped Nanocrystal
Hongyue Wang, Emmanuel Lhuillier, Qian Yu +4
Addressing the optical properties of a single nanoparticle in the infrared is particularly challenging, thus alternative methods for characterizing the conductance spectrum of nano…
Superconducting parity effect across the Anderson limit
Sergio Vlaic, Stéphane Pons, Tianzhen Zhang +7
How small superconductors can be? For isolated nanoparticles subject to quantum size effects, P.W. Anderson conjectured in 1959 that superconductivity could only exist when the ele…
Metal oxide resistive switching: evolution of the density of states across the metal-insulator transition
Alireza Mottaghizadeh, Qian Yu, Pei Lin Lang +2
We report the study of metal-STO-metal memristors where the doping concentration in STO can be fine-tuned through electric field migration of oxygen vacancies. In this tunnel junct…
Quantum confinement effects in Pb Nanocrystals grown on InAs
Tianzhen Zhang, Sergio Vlaic, Stéphane Pons +9
In the recent work of Ref.\cite{Vlaic2017-bs}, it has been shown that Pb nanocrystals grown on the electron accumulation layer at the (110) surface of InAs are in the regime of Cou…
