Silicon Nitride Nanopillars and Nanocones Formed by Nickel Nanoclusters and Inductively Coupled Plasma Etching for Solar Cell Application

Abstract

We discuss the contribution of OZI-suppressed diagrams to the hyperfine splitting of charmonium in lattice QCD. We study valence quark mass regions from strange to charm quark masses. No contribution of the disconnected diagram is seen in the vector meson channel. In the pseudo-scalar channel and for valence quark masses around the strange quark, the disconnected contribution induces a considerable increase of the meson mass. This contribution quickly decreases as the quark mass increases. For charmonium the effect is very small although a decrease of the pseudoscalar mass induced by the disconnected contribution cannot be ruled out.

Simulation of a high-efficiency and low-jitter nanostructured silicon single-photon avalanche diode

“…In addition to better device performance, this nanostructure is easy to fabricate. A silicon nitride nanocone structure can be made by applying a self-assembled nickel nanoparticle and dry etching [36]. The double-sided nanocone structure can be processed sequentially, and one may even directly process on a thin-film silicon wafer [37].…”

Broadband anti-reflection coating using dielectric Si3N4 nanostructures. Application to amorphous-Si-H solar cells

“…Si 3 N 4 thin film Anti-Reflection Coating (ARC) has been positively proved, with optimum thickness values of 60 nm [16,17]. Dielectric subwavelength nanostructures have also been proposed to enhance efficiency for Si-based solar cells [18][19][20][21]. In some cases, the proposed structures have been fabricated and realized in practice.…”

Engineered biomimicry for harvesting solar energy: a bird's eye view

“…and coefficient of thermal expansion. Randomly sized and spaced pyramids [14,18,19], deep vertical-wall grooves [20], V grooves [21,22], and arrays of nanopillars [6][7][8][9][10][11]23] on the surface of silicon wafers have been widely utilized to reduce optical reflectance. Several surface-texturing techniques [24] including anodization [25] have also been used.…”
