Abstract Platinum diselenide (PtSe2) is a promising two‐dimensional (2D) material for the terahertz (THz) range as, unlike other transition metal dichalcogenides (TMDs), its bandgap can be uniquely tuned from a semiconductor in the near‐infrared

We introduce a response theory based transformation for excitonic polarizability into mobility, which allows an in-depth analysis of optical pump–THz probe conductivity experiments, and compare the results with those of a conventional oscillator mo

Structural defects can crucially impact the optical response of monolayer (ML) thick materials as they enable trapping sites for excitons. These trapped excitons appear in photoluminescence spectra as new emissions below the free bright exciton and i

We investigate the lateral size tunability of the exciton diffusion coefficient and mobility in colloidal quantum wells by means of line width analysis and theoretical modeling. We show that the exciton diffusion coefficient and mobility in laterally

We present a theoretical study combined with experimental validations demonstrating that CdSe nanoplatelets are a model system to investigate the tunability of trions and excitons in laterally finite 2D semiconductors. Our results show that the trion

Disorder derived from defects or strain in monolayer TMDs can lead to a dramatic change in the physical behavior of the interband excitations, producing inhomogeneous spectral broadening and localization; leading to radiative lifetime increase. In th

The investigation of the fluctuations and their influence on the exciton in the perovskite structure is topical. These fluctuations can be due to the prolongation of the annealing or the increasing of the temperature in the perovskite monolayers. Thi
