Abstract
The coupling of excitons in MoSe2, WSe2, or other similar TMD materials to optical cavities is a branch of solid state physics that has been rarely studied. However, the energy of the coupled oscillation can provide an interesting look into the behavior of excitons when exposed to an electromagnetic field. To take this dive into the mechanics of the solid states, we will utilyze Scotch tape exfoliation to create TMD samples that we will then analyze via its emitted photoluminescence spectra. By placing these TMD materials on an optical nanocavity, we can couple the oscillation of light waves to the oscillation of the exposed exciton-polariton pair, thereby understanding the behavior of these quasiparticles under the influence of an electromagnetic field. Upon the completion of this integration, we expect to measure a PL spectra in the 720-750 nm wavelengths, corresponding to an energy of 2.76 * 10^-19 J photons. This energy is a testament to the oscillation strength of the exciton, helping to explain the binding strength of the electron – hole pairs of the exciton quasiparticles. Understanding this is especially important for an in-depth account of the quantum mechanical properties of solids, especially in terms of the behavior of electrons. With an increased understanding of electrons, various solid state and semiconductor technologies can utilize the interesting properties of TMD materials in more and more complex systems.
