We report the influence of uniaxial tensile mechanical strain in the range 0–2.2% on the
phonon spectra and bandstructures of monolayer and bilayer molybdenum disulfide (MoS2) …

Geometrical confinement effect in exfoliated sheets of layered materials leads to significant
evolution of energy dispersion in mono-to few-layer thickness regime. Molybdenum disulfide …

Exciton binding energy and excited states in monolayers of tungsten diselenide (WSe 2) are
investigated using the combined linear absorption and two-photon photoluminescence …

We report on a strong photoluminescence (PL) enhancement of monolayer MoS2 through
defect engineering and oxygen bonding. Micro-PL and Raman images clearly reveal that …

Point defects in semiconductors can trap free charge carriers and localize excitons. The
interaction between these defects and charge carriers becomes stronger at reduced …

Single-and few-layer crystals of exfoliated MoTe2 have been characterized
spectroscopically by photoluminescence, Raman scattering, and optical absorption …
