“Background Quantum dot superlattices (QDSLs) have attracted a great deal of interest from both physical scientists and device researchers. Tucidinostat price Electron wave functions diffuse and overlap, which merge discrete quantum levels into minibands, with quantum dots approaching and forming a quasi-crystal structure. This band rearrangement has significant applications for many novel optoelectronic/electronic
devices [1–15]. For example, quantum dot solar cells, the most exciting photovoltaic device with more than 63% conversion efficiency, have to utilize minibands for carrier transport and additional optical transitions. Ideal QDSLs present a great challenge to current nanotechnologies. Several technologies
(e.g., chemical solution methods and molecular beam epitaxy (MBE)) have convincingly been used to fabricate relatively uniform quantum dots; however, very few technologies can finitely arrange QDs to form a quasi-crystal structure. The well-developed MBE technology can only achieve very limited control on the direction of growth, which induces a mixed state with the wetting layer. The most direct idea is to develop a top-down nanotechnology. However, nanometer-order sizes VS-4718 exceed most light/electron beam limitations, mafosfamide and suitable masks seem impossible to create. The neutral beam (NB) etching and ferritin bio-template we developed have recently brought about a great breakthrough in that we successfully fabricated two-dimensional (2D) array Si nanodisks (Si-NDs) with sub-10 nm, high density (>1011 cm-2), and quasi-hexagonal crystallization [16–20]. Photovoltaic conversion efficiency was determined by light absorbance and carrier collection efficiency. Our previous work has proven that wave function coupling relaxes the selection rule to induce additional optical transitions [21, 22]. We first observed enhanced conductivity in 2D and three-dimensional (3D) array Si-NDs with a SiC matrix in this study.
