Dual Universality and Unconventional Phase Diagram of a Clean 2D Superconductor with Tunable Disorders
Puhua Wan, Qihong Chen, Oleksandr Zheliuk +4
Weakly disordered two-dimensional (2D) superconductors can host richer quantum phase transitions than their highly-disordered counterparts. This is due to the insertion of a metall…
Magnetic tunnel junctions based on ferroelectric Hf0.5Zr0.5O2 tunnel barriers
Yingfen Wei, Sylvia Matzen, Guillaume Agnus +7
A ferroelectric tunnel barrier in between two ferromagnetic electrodes (multiferroic tunnel junction, MFTJ), is one of the most promising concepts for future microelectronic device…
Gate-Controlled Magnetoresistance of a Paramagnetic Insulator|Platinum Interface
L. Liang, J. Shan, Q. H. Chen +6
We report an electric field-induced in-plane magnetoresistance of an atomically flat paramagnetic insulator|platinum (Pt) interface at low temperatures with an ionic liquid gate. T…
Possible charge-density-wave signatures in the anomalous resistivity of Li-intercalated multilayer MoS2
Erik Piatti, Qihong Chen, Mauro Tortello +2
We fabricate ion-gated field-effect transistors (iFET) on mechanically exfoliated multilayer MoS. We encapsulate the flake by AlO, leaving the device channel exposed at…
Inducing ferromagnetism and Kondo effect in platinum by paramagnetic ionic gating
L. Liang, Q. H. Chen, J. M. Lu +5
Electrically controllable magnetism, which requires the field-effect manipulation of both charge and spin degrees of freedom, has attracted growing interests since the emergence of…
