Atomically thin transition metal dichalcogenides (TMDs) are 2D semiconductors with tightly
bound excitons and correspondingly strong light–matter interactions. Owing to the weak van …

Designing efficient and cost-effective materials is pivotal to solving the key scientific and
technological challenges at the interface of energy, environment, and sustainability for …

Semiconducting two-dimensional materials with chemical formula MoSi2X4 (X= N, P, or As)
are studied by means of atomistic ground-and excited-state first-principles simulations. Full …

The existence of bound charge transfer (CT) excitons at the interface of monolayer lateral
heterojunctions has been debated in literature, but contrary to the case of interlayer excitons …

Quantum confinement effects and structures with broken inversion symmetry distinguish
transition metal halide (TMD) monolayers from their bulk equivalents in several ways, for …

The interlayer coupling is emerging as a new parameter for tuning the physical properties of
two-dimensional (2D) van der Waals materials. When two identical semiconductor …

Potential applications in photonics and optoelectronics are based on our understanding of
the light–matter interaction on an atomic monolayer scale. Atomically thin 2D transition metal …

Mechanical deformations and ensuing strain are routinely exploited to tune the band gap
energy and to enhance the functionalities of two-dimensional crystals. In this Letter, we show …

Transition metal dichalcogenides (TMDCs) are ideal candidates to explore the manifestation
of spin-valley physics under external stimuli. In this study, we investigate the influence of …

External fields are a powerful tool to probe optical excitations in a material. The linear
energy shift of an excitation in a magnetic field is quantified by its effective g factor. Here we …
