Crystallization of amorphous silicon thin films using nanoenergetic intermolecular materials with buffer layers

Nanostructured Energetic Composites: Synthesis, Ignition/Combustion Modeling, and Applications

“…Crystallization of amorphous silicon with nanoenergetic composites is advantageous for its local heating and swift processing, and is suitable for large area production. 139,141 Figure 9 shows a schematic of the crystallization of amorphous silicon induced by thermite reaction of Al/Fe 2 O 3 nanocomposite. SiO 2 and Ag layers were deposited to prevent metal diffusion during processing and retain thermal energy transportation.…”

“…The residual products and Ag/SiO 2 buffer layers were etched away after the reaction to leave the crystallized poly-Si thin film. 139 4.4. Micro-Actuation/Propulsion.…”

An extremely superhydrophobic and intrinsically stable Si/fluorocarbon energetic composite based on upright nano/submicron-sized Si wire arrays

“…[1][2][3][4] The potential applications of nanoenergetic materials are versatile, such as ignition and propulsion in the defence industry, 5,6 initiators for air bags and belt-tensioners in the automobile industry, 7,8 microuidics actuation, molecular delivery, and biocidal effect in biomedicine, [9][10][11] and materials synthesis and processing in materials science and engineering. 12,13 More than two decades has passed since the advent of the idea. Among the numerous studies, some features are always the pursuits of researchers, such as the superior and controllable energetic capability, the cost-effective and environment-benign synthesis method, and the reliability of function and stability during storage.…”

Highly Exothermic and Superhydrophobic Mg/Fluorocarbon Core/Shell Nanoenergetic Arrays

“…Nanoenergetic materials (nEMs) have received steadily growing interest because of the improved performance in ignition, combustion, and energy release. 1−4 They have broad potential applications in both civilian and military fields, including microignition and rapid initiation, 5−7 gas generators, 8,9 microactuation, 10,11 burn rate modifiers, 12,13 synthesis and processing of materials, 14,15 and biomedicine-related applications. 16,17 Ultrasonic mixing of nanoscale fuel and oxidizer particles is widely employed as an efficient way to prepare nanoenergetic composites.…”

However, the passivation shell around the nanometal behaves as a noticeable “dead weight” (especially for particle diameters < 50 nm), which will decrease the energy density as well as inhibit combustion propagation. , Moreover, the nonhomogeneous distribution of fuel and oxidizer can cause scattering in the ignition and combustion performance .…”
