Semimetal-to-semiconductor transition and charge-density-wave melting in $1 T$ -TiSe $_{2 - x}$ S $_{x}$ single crystals

M. -L. Mottas, T. Jaouen, B. Hildebrand +9

The transition metal dichalcogenide $1 T$ -TiSe $_{2}$ is a quasi-two-dimensional layered material with a phase transition towards a commensurate charge density wave (CDW) at a critical…

Excited States at Interfaces of a Metal-Supported Ultrathin Oxide Film

T. Jaouen, E. Razzoli, C. Didiot +5

We report layer-resolved measurements of the \textit{unoccupied} electronic structure of ultrathin MgO films grown on Ag(001). The metal-induced gap states at the metal/oxide inter…

Unveiling the Semimetallic Nature of 1 $T$ -TiSe $_{2}$ by Doping its Charge Density Wave

T. Jaouen, M. Rumo, B. Hildebrand +10

The semimetallic or semiconducting nature of the transition metal dichalcogenide 1 $T$ -TiSe $_{2}$ remains under debate after many decades mainly due to the fluctuating nature of its 2…

Phase Separation in the Vicinity of Fermi Surface Hot Spots

T. Jaouen, B. Hildebrand, M. -L. Mottas +12

Spatially inhomogeneous electronic states are expected to be key ingredients for the emergence of superconducting phases in quantum materials hosting charge-density-waves (CDWs). P…

Local resilience of the $1 T$ -TiSe $_{2}$ charge density wave to Ti self-doping

B. Hildebrand, T. Jaouen, C. Didiot +10

In Ti-intercalated self-doped $1 T$ -TiSe $_{2}$ crystals, the charge density wave (CDW) superstructure induces two nonequivalent sites for Ti dopants. Recently, it has been shown that…
