Insights into the generation of laser-induced assembly of MoSe2 nanospheres

Combined simulation and experimental study on spectral absorbance of partially disordered MoSe2 nanospheres

“…narrow band gap and high photo-response [7][8][9]. Nowadays, the properties of partially disordered MoSe 2 nanospheres have been investigated a lot and widely applied in the areas of nonlinear optics [10], photothermal agent [11] and laser-induced assembly [12]. However, there is still a lack of operable method and effective parameter analysis to reveal the high optical absorption feature of partially disordered MoSe 2 nanospheres by employing a three-dimensional (3D) model with optical simulation and numerical computation.…”

A Single MoSe2 Fluffy Nanosphere for Localized Light Confinement

“…16,17 However, few studies have been conducted to reveal the inherent mechanism underlying the optical properties by building a three-dimensional (3D) model with the topological constraint of a single MoSe 2 fluffy nanosphere. The modeling approach is also useful to facilitate an in-depth analysis of other semiconductor materials and broaden the potential applications, such as nanolithography, 17 nanopattern manufacturing, 18 and tip-enhanced Raman scattering. 19 Furthermore, it has been well-known that the focusing feature and roles of dielectric microspheres (e.g., PS, silicon, and silica) can be applied in advanced techniques, such as super-resolution optical imaging 7 and all-optical processing.…”

“…It has fast carrier mobility and high photoresponse. Both micro- and nanospheres of MoSe 2 have been applied to various fields, such as optoelectronics, photocatalysts, photodetectors, photothermal agents and optical tweezers . The novel features of MoSe 2 fluffy nanospheres including broad-band absorption, optical nonlinearity, and predesigned assembly with the modulation of an incident optical field were investigated in recent studies. , However, few studies have been conducted to reveal the inherent mechanism underlying the optical properties by building a three-dimensional (3D) model with the topological constraint of a single MoSe 2 fluffy nanosphere.…”
