Electrons imitating light: Frustrated supercritical collapse in charged arrays on graphene
Jiong Lu, Hsin-Zon Tsai, Alpin N. Tatan +10
The photon-like electronic dispersion of graphene bestows its charge carriers with unusual confinement properties that depend strongly on the geometry and strength of the surroundi…
Mapping multi-valley Lifshitz transitions induced by field-effect doping in strained MoS2 nanolayers
Erik Piatti, Davide Romanin, Renato S. Gonnelli
Gate-induced superconductivity at the surface of nanolayers of semiconducting transition metal dichalcogenides (TMDs) has attracted a lot of attention in recent years, thanks to th…
Towards the insulator-to-metal transition at the surface of ion-gated nanocrystalline diamond films
Erik Piatti, Francesco Galanti, Giulia Pippione +2
Hole doping can control the conductivity of diamond either through boron substitution, or carrier accumulation in a field-effect transistor. In this work, we combine the two method…
Ambipolar suppression of superconductivity by ionic gating in optimally-doped BaFe2(As,P)2 ultrathin films
Erik Piatti, Takafumi Hatano, Dario Daghero +9
Superconductivity (SC) in the Ba-122 family of iron-based compounds can be controlled by aliovalent or isovalent substitutions, applied external pressure, and strain, the combined…
Anomalous screening of an electrostatic field at the surface of niobium nitride
Erik Piatti, Davide Romanin, Renato S. Gonnelli +1
The interaction between an electric field and the electric charges in a material is described by electrostatic screening, which in metallic systems is commonly thought to be confin…
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…
