Heterostructures (HSs) formed by the transition-metal dichalcogenide materials have shown great promise in next-generation (opto)electronic applications. An artificially twisted HS allows us to manipulate the optical and electronic properties. In this work, we introduce the understanding of the energy transfer (ET) process governed by the dipolar interaction in a twisted molybdenum diselenide (MoSe) homobilayer any charge-blocking interlayer.

Systematic dependence of the RS process efficiency on the energy of the laser excitation is explored for four different excitation energies: 1.96 eV, 2.

- The optical behavior of 2D perovskites relies heavily on excitons, which can be manipulated by altering the thickness of the perovskite layers.
- Researchers studied the exciton fine structure in a specific 2D perovskite by varying the number of inorganic layers from 1 to 4.
- Their findings reveal splitting of excitonic states across different confinement levels and show how the optical properties transition from 2D to 3D as the layer thickness increases.
Moiré excitons (MXs) are electron-hole pairs localised by the periodic (moiré) potential forming in two-dimensional heterostructures (HSs). MXs can be exploited, e.g.

Two samples were tested: a sample which contained ten QWs (MQW) and a sample with one QW (SQW).
