- W4379419562 abstract "We investigate the optical properties of two-dimensional monolayer films of MoSe<sub>2</sub> and WSe<sub>2</sub> (each 0.7nm thick) assembled on SiO<sub>2</sub>/Si substrates (285nm/0.5mm thick). These films are interesting because they are direct band gap semiconductors that have large excitonic responses. However, due to numerous challenges, including the lack of a quick, contactless, and reliable method, obtaining the optical constants and exciton binding energies in-situ remains a difficult endeavor. Here, we report the optical properties based on contactless ellipsometry to retrieve the optical constants (n,k) and excitonic properties of both monolayers (MoSe<sub>2</sub> and WSe<sub>2</sub>). The optical properties of these materials away from the exciton (~700 nm) are generally not well understood. In this work, we will explore the optical response of these films over a broad range that includes the UV/visible and near infrared (200-2000nm) in order to understand if there are other spectral regions with a strong or tunable refractive index. The current samples are intrinsic without doping. The SiO<sub>2</sub> on the Si substrate would be used as a gate capacitor which would allow to vary the density by ~10<sup>11</sup>-10<sup>12</sup> cm<sup>-2</sup>. These transition metal dichalcogenides (TMD) offer new possibilities for designing modern photonic and optoelectronic components." @default.
