Quantum tailoring of electronic properties in covalently functionalized graphene: application to ammonia gas detection
A. Dammak, F. Raouafi, A. Cavanna +5
Functionalized graphene offers great potential in the field of rapid detection of gases at room temperature. We performed first-principles calculations to study the suitability of…
Assessment of GaPSb/Si tandem material association properties for photoelectrochemical cells
Lipin Chen, Mahdi Alqahtani, Christophe Levallois +12
Here, the structural, electronic and optical properties of the GaP1-xSbx/Si tandem materials association are determined in view of its use for solar water splitting applications. T…
Potential-inserted quantum well design for quantum cascade terahertz lasers
R. Benchamekh, J. -M. Jancu, P. Voisin
We report on a new design of terahertz quantum cascade laser based on a single, potential-inserted quantum well active region. The quantum well properties are engineered through si…
Tight-binding calculations of image charge effects in colloidal nanoscale platelets of CdSe
R. Benchamekh, N. A. Gippius, J. Even +6
CdSe nanoplatelets show perfectly quantized thicknesses of few monolayers. They present a situation of extreme, yet well defined quantum confinement. Due to large dielectric contra…
An electronic model for self-assembled hybrid organic/perovskite semiconductors: reverse band edge electronic states ordering and spin-orbit coupling
J. Even, L. Pedesseau, M. -A. Dupertuis +2
Based on density functional theory, the electronic and optical properties of hybrid organic/perovskite crystals are thoroughly investigated. We consider the mono-crystalline 4FPEPI…
STM images of sub-surface Mn atoms in GaAs: evidence of hybridization of surface and impurity states
J. -M. Jancu, J. -Ch. Girard, M. Nestoklon +3
We prove that scanning tunneling microscopy (STM) images of sub-surface Mn atoms in GaAs are formed by hybridization of the impurity state with intrinsic surface states. They canno…
