Solution-processed, large-area, and flexible electronics largely relies on the excellent electronic properties of sp$^2$-hybridized carbon molecules, either in the form of $\pi$-conjugated small molecules and polymers or graphene and carbon nanotubes. Carbon with sp-hybridization, the foundation of the elusive allotrope carbyne, offers vast opportu...

Hybrid quantum wells are electronic structures were charge carriers are confined along stacked inorganic planes, separated by insulating organic moieties. 2D quantum confined hybrid materials are of great interest from...

2D quantum confined hybrid materials are of great interest from a solid state physics standpoint because of the rich multibody phenomena hosted, their tunability and easy synthesis allowing to create material libraries. In addition, from a technological standpoint, 2D hybrids are promising candidates for efficient, tunable, low cost materials impac...

Silver benzeneselenolate [AgSePh] is a coordination polymer that hosts a hybrid quantum well structure. The recent advancements in the study of its tightly bound excitons (~300 meV) and photoconductive properties makes it an interesting representative of a material platform that is an environmentally stable alternative to 2D metal halide perovskite...

Understanding thermal transport in 2D materials and especially in graphene is a key challenge for the design of heat management and energy conversion devices. The high sensitivity of measured transport properties to structural defects, ripples and vacancies is of crucial importance in these materials. Using a first principle based approach combined...

The thermoelectric properties of single layer transition metal dichalchogenide MoS2 are investigated on the basis of ab initio calculations combined with the Landauer formalism. The focus is made on sulfur vacancy defects which are observed experimentally to be massively present in such material especially for exfoliated two dimensional MoS2. The i...

Carbyne and linear carbon structures based on sp-hybridization are attractive targets as the ultimate 1D system (i.e., one-atom in diameter) featuring wide tunability of optical and electronic properties.1–3 Two possible structures exist for sp-carbon atomic wires a) the polyynes with alternated single-triple bonds, and b) the cumulenes with contig...

Dilute suspensions of repulsive particles exhibit a Newtonian response to flow that can be accurately predicted by the particle volume fraction and the viscosity of the suspending fluid. However, such a description fails when the particles are weakly attractive. In a simple shear flow, suspensions of attractive particles exhibit complex, anisotropi...
