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…

Short-range phase coherence and origin of the 1T-TiSe2 charge density wave

B. Hildebrand, T. Jaouen, C. Didiot +9

The impact of variable Ti self-doping on the 1T-TiSe2 charge density wave (CDW) is studied by scanning tunneling microscopy. Supported by density functional theory we show that agg…

Local Real-Space View of the Achiral 1 $T$ -TiSe $_{2}$ 2 $\times$ 2 $\times$ 2 Charge Density Wave

B. Hildebrand, T. Jaouen, M. -L. Mottas +5

The transition metal dichalcogenide 1 $T$ -TiSe $_{2}$ is a quasi-two-dimensional layered material undergoing a commensurate 2 $\times$ 2 $\times$ 2 charge density wave (CDW) transition…

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…

Selective probing of hidden spin-polarized states in inversion-symmetric bulk MoS2

E. Razzoli, T. Jaouen, M. -L. Mottas +13

Spin- and angle-resolved photoemission spectroscopy is used to reveal that a large spin polarization is observable in the bulk centrosymmetric transition metal dichalcogenide MoS2.…

STM microscopy of the CDW in 1T-TiSe2 in the presence of single atom defects

A. M. Novello, B. Hildebrand, A. Scarfato +7

We present a detailed low temperature scanning tunneling microscopy study of the commensurate charge density wave (CDW) in 1 $T$ -TiSe $_{2}$ in the presence of single atom defects. We…

Impact of Electron-Hole Correlations on the 1T-TiSe2 Electronic Structure

G. Monney, C. Monney, B. Hildebrand +2

Several experiments have been performed on 1T-TiSe2 in order to identify whether the electronic structure is semimetallic or semiconducting without reaching a consensus. In this pa…

Doping nature of native defects in 1T-TiSe2

B. Hildebrand, C. Didiot, A. M. Novello +7

The transition metal dichalcogenide 1T-TiSe2 is a quasi two-dimensional layered material with a charge density wave (CDW) transition temperature of TCDW 200 K. Self-doping effects…
