Intrinsic defects and mid-gap states in quasi-one-dimensional Indium Telluride
Meryem Bouaziz, Aymen Mahmoudi, Geoffroy Kremer +9
Recently, intriguing physical properties have been unraveled in anisotropic semiconductors, in which the in-plane electronic band structure anisotropy often originates from the low…
Positional and Rotational Molecular Degrees of Freedom in a Metal-Organic Surface Alloy: the Copper-Fullerene System and its Multiple Structural Phases
María Alfonso Moro, Yannick Dappe, Sylvie Godey +7
Mixing two chemical elements at the surface of a substrate is known to produce rich phase diagrams of surface alloys. Here, we extend the concept of surface alloying to the case wh…
Phase-Space Ab-Initio Direct and Reverse Ballistic-Electron Emission Spectroscopy: Schottky Barriers Determination for Au/Ge(100)
Andrea Gerbi, Renato Buzio, Cesar Gonzalez +2
We develop a phase-space ab-initio formalism to compute Ballistic Electron Emission Spectroscopy current-voltage I(V)'s in a metal-semiconductor interface. We consider injection of…
Dispersing and semi-flat bands in the wide band gap two-dimensional semiconductor bilayer silicon oxide
G. Kremer, J. C. Alvarez-Quiceno, T. Pierron +11
Epitaxial bilayer silicon oxide is a transferable two-dimensional material predicted to be a wide band gap semiconductor, with potential applications for deep UV optoelectronics, o…
Electronic band structure of ultimately thin silicon oxide on Ru(0001)
G. Kremer, J. C. Alvarez-Quiceno, S. Lisi +12
Silicon oxide can be formed in a crystalline form, when prepared on a metallic substrate. It is a candidate support catalyst and possibly the ultimately-thin version of a dielectri…
A single hydrogen molecule as an intensity chopper in an electrically-driven plasmonic nanocavity
Pablo Merino, Anna Rosławska, Christopher C. Leon +5
Photon statistics is a powerful tool for characterizing the emission dynamics of nanoscopic systems and their photophysics. Recent advances that combine correlation spectroscopy wi…
Weakly Trapped, Charged, and Free Excitons in Single-Layer MoS2 in the Presence of Defects, Strain, and Charged Impurities
Sudipta Dubey, Simone Lisi, Goutham Nayak +17
Few- and single-layer MoS2 host substantial densities of defects. They are thought to influence the doping level, the crystal structure, and the binding of electron-hole pairs. We…
Interactions between two C60 molecules measured by scanning probe microscopies
Nadine Hauptmann, César González, Fabian Mohn +3
C60-functionalized tips are used to probe C60 molecules on Cu(111) with scanning tunneling and atomic force microscopy. Distinct and complex intramolecular contrasts are found. Max…
Pulling and Stretching a Molecular Wire to Tune its Conductance
Gaël Reecht, Hervé Bulou, Fabrice Scheurer +5
A scanning tunnelling microscope is used to pull a polythiophene wire from a Au(111) surface while measuring the current traversing the junction. Abrupt current increases measured…
